Fedora 39 : GitHub tickets.

You can get a free virtual ticket for a price of 0.

Datatime and Location: NOVEMBER 8—9 LIVE & VIRTUAL YERBA BUENA CENTER FOR THE ARTS, SAN FRANCISCO.

Fedora 39 : micro - terminal .

micro - a modern and intuitive terminal-based text editor, see more on this official website.

Let's see how works n Fedora 39 Linux Distro ...

Fedora 39 : Test Day:2023-08-11 Fedora 39 DNF 5

See more about this test with DNF5 on this wiki webpage and on this test results webpage.

Fedora 38 : Sway on VirtualBox.

Sway is a tiling Wayland compositor and a drop-in replacement for the i3 window manager for X11. It works with your existing i3 configuration and supports most of i3's features, plus a few extras.

You can find this desktop at this GitHub project.

The official webpage comes with a video tutorial on how to use it.

Installation is simple with these commands using the dnf tool:

# dnf group install sway-desktop-environment
# dnf install sway-config-fedora

It is possible to ask you for additional arguments for installation like this: --allowerasing or --skip-broken.

After installation, reboot and select sway from the desktop switcher

NOTE: The display for virtual video card from VirtualBox need to be set to Enable 3D Acceleration.

Let's see the result of this desktop environment ...

Fedora 38 : Openbox from GitHub.

I tried to use the OpenBox desktop environment in Fedora 38 and it seems to be incomplete, see also this thread.

I try to build the Openbox desktop from the source code, see the GitHub project.

$ git clone https://github.com/danakj/openbox.git
$ cd openbox

I need to install these: gettext-devel, glib2-devel, libtool, and pango-devel.X86_64 all devel libraries with dnf tool ...

Use the next commands, you will see some errors about some deprecated libraries and source code when you use the make command.

$ ./bootstrap
$ ./configure
$ make 

The go-to openbox folder to see the result:

$ cd openbox
$ ls -lFGC

The last step is to run the Openbox after you solve these:

Failed to open the display from the DISPLAY environment variable.

Openbox-Message: A window manager is already running on screen 0.

Because you are into environment area you need to close it.

After several attempts, I managed to pass these issues and ran the command:

$ ./xinit

This is the result is this:

I don't really have skills in this field of changes in Linux distributions and I wouldn't want to give wrong indications.

Fedora 38 : Deepin on VirtualBox.

Today, I tested the Deepin environment on Virtual Box where I installed Fedora 38.

I do not recommend using this desktop environment on Virtual Box because it requires graphics resources.

Installation is simple as with any desktop environment installation, see this official webpage.

Here is the final result:

Fedora 39 : FASM tool in Fedora.

I searched the internet about the FASM tool and found references that it would be included in the Ubuntu distribution.

If you want to use FASM with the related language in the Fedora Linux distribution, then find the commands in the image below:

Fedora 39 : Test with eDEX-UI.

eDEX-UI is a fullscreen, cross-platform terminal emulator and system monitor that looks and feels like a sci-fi computer interface.

This can be found on this GitHub project.

This is version for 64-bit Machines, you can download it with:

$ wget -c https://github.com/GitSquared/edex-ui/releases/download/v2.2.8/eDEX-UI-Linux-x86_64.AppImage

Change the file to be executable:

$ chmod +x eDEX-UI-Linux-x86_64.AppImage

Use this command:

$ ./eDEX-UI-Linux-x86_64.AppImage --appimage-extract

Go to this folder:

$ cd squashfs-root

Run the application:

$ ./AppRun

This is the result of running the application:

Fedora 39 : Resize the vdi file for VirtualBox.

NOTE : This will not change the size of the Linux partition. I tried to change the size in fedora linux with specific commands, but I didn't succeed. The distribution I tried was a server without a graphical environment so I could also try gparted software.

It is good to use the Fedora Linux distribution for tests and feedback to the Fedora team on a hardware system, such as an old laptop.

For quick tests and to save time, you can also install a version on VirtualBox, and sometimes you may not have enough space on the virtual disk.

You can try a tool called VBoxManage with this command to your named vdi file:

VBoxManage modifyhd "C:\Fedora\Fedora.vdi" --resize 81920

You may receive this error:

0%...VBOX_E_NOT_SUPPORTED
VBoxManage.exe: error: Failed to resize medium
VBoxManage.exe: error: Resizing to new size 190756945920 is not yet supported for medium 'C:\Fedora\Fedora.vdi'
VBoxManage.exe: error: Details: code VBOX_E_NOT_SUPPORTED (0x80bb0009), component MediumWrap, interface IMedium
VBoxManage.exe: error: Context: "enum RTEXITCODE __cdecl handleModifyMedium(struct HandlerArg *)" at line 937 of
file VBoxManageDisk.cpp

You can check information about the vdi file on which the Fedora distribution is installed with this command:

VBoxManage showhdinfo "C:\Fedora\Fedora.vdi"

Make a clone of the vdi file.

VBoxManage clonehd "C:\Fedora\Fedora.vdi" "C:\Fedora\Fedoracloned.vdi"
...
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Clone medium created in format 'VDI'. UUID: ...

Resize this cloned virtual disk with this command:

VBoxManage modifyhd "C:\Users\catafest\VirtualBox VMs\Fedora\Fedoracloned.vdi" --resize 30000
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Fedora 39 : DNF, DNF-3 and DNF5

Before installing DNF5 you should know that your installations with this tool in the fedora distribution may not work correctly

After implementation of dnf5 module install dnf and dnf5 cannot share the same location for storing state of modules, because dnf5 will store additional information about installed profiles (braking change). Modules enabled by DNF5 (dnf5 module enable <module>) will be not seen as enabled in DNF. Module profile installed by DNF5 will be not sees as installed in DNF. DNF will only see installed RPMs.

More details on this official webpage.

You can fix it with the dnf-3 tool if you accidentally modified or deleted the dnf tool.

A simple example is installing Deepin Desktop, which I could only install with DNF-3:

# dnf-3 install @deepin-desktop

The other dnf and dnf5 tools didn't work, I didn't wait to check if it's because of the repos. but it did not bring me the packets from the web and shows me transactions of 0 B.

Fedora 39 : First test with C# and Terminal.Gui.templates.

The current, stable, release of Terminal.Gui is v1.x. It is stable, rich, and broadly used. The team is now focused on designing and building a significant upgrade we're referring to as v2.

You can find it on this GitHub project.

$ dotnet new --install Terminal.Gui.templates
$ dotnet new tui -n test001
$ cd test001
$ dotnet run

Fedora 39 : Install and fix error with dotnet and copr.

Copr is an easy-to-use automatic build system providing a package repository as its output.

Free/Open source software that is harder to include in Fedora (usually because it is developed in a way that makes it difficult to package while implementing the Fedora packaging guidelines) is temporarily provided in an extra COPR repository, see the official webpage.

I tried to install dotnet following a tutorial on Fedora Magazine:

# dnf copr enable @dotnet-sig/dotnet

I obviously received errors related to copr, because is not install and I used Fedora 39, since Fedora 39 is still Rawhide.

I try to install copr with dnf5:

# dnf5 install copr

I got some errors on python-request-2.28.2-2.fc39.noarch conflicts with new one requested by dnf5 and I remove this package and I let to install the new one.

I try again with same command:

# dnf5 install copr

The next command was:

$ sudo dnf copr enable @dotnet-sig/dotnet fedora-38-x86_64

This allow me to use fedora-38-x86_64 and warn me about copr.

Enabling a Copr repository. Please note that this repository is not part
of the main distribution, and quality may vary ...

The last one is to install .NET Core:

# dnf5 install dotnet

This install all packages for .NET Core with SDK version 6.0 .

I tested with a simple project:

$ dotnet new console -o mythcat_console
$ cd mythcat_console
$ dotnet run 
Hello, World!

This is the way that can use Fedora packages with copr.

Fedora 39 : Solve copy-paste in VirtualBox.

I'm using the Fedora 39 Linux distribution on an HP laptop and I also have it installed on a VirtualBox on my work computer. Today I will show you a way to solve copy paste between content on your computer and Fedora 39 on VirtualBox.

This requires Virtual Box to be set to bridge network as in the attached image.

The next step is to have the Cockpit tool installed, see instructions here.

Open the web address created by the Cockpit tool in your computer browser and go to the Terminal section. This way you will be able to transfer text content using your computer's browser and not the VirtualBox settings.

See the next image:

News : About my work and one of my websites.

I would like to bring to the attention of those who follow my activity on my websites and appreciate the inability to continue with one of the websites: free-tutorials.org. It is currently hosted on a free host, but I cannot import it 100%, which has led me not to complete it with new posts. The continuation of the activities there, considering the limited time, will be carried out on my blogs with the defined theme with which I started: Linux - Fedora, Graphics, Python, Pygame.

In the meantime, because the host is expensive and until now someone has helped me to host it on his server, it is possible to sell the domain: free-tutorials.org - I receive purchase offers at my personal Yahoo email address catafest@yahoo.com.

Minimum starting price 250 euros, because the domain is old from 2018.

Fedora 39 : DNF5 error update.

Sometimes errors may occur when installing Fedora packages using the dnf or dnf5 utility. One of the reasons may result from the coincidence of the package installation process. If you know how to build packages, how to develop the Fedora team, and how many repositories you have set up in your Linux distribution, then such an error can be easily fixed. Here is the error:

First, install the dnf5 and dnf5-plugins with this command:

sudo dnf install dnf5 dnf5-plugins

One good way to fix error is to have defined settings in : /etc/dnf/dnf.conf in order to have a good installation flow and how to link packages to the interconnected job.

See my example that fix this error:

Some packages may conflict in the repo and you can check with the dnf info fedora_repo_package command.

For example, you can use exclude=*.noarch in the [main] area.

News : The new DNF5 tool is on Fedora .

The new DNF5 will provide a significant improvement in user experiences and performance. The replacement is the second step in upgrade of Fedora Software Management stack. Without the change there will be multiple software management tool (DNF5, old Microdnf, PackageKit, and DNF) based on different libraries (libdnf, libdnf5), providing a different behavior, and not sharing a history and module state. We can also expect that DNF will have only limited support from upstream. The DNF5 development was announced on Fedora-Devel list in 2020.

You can read more on the official webpage on Fedora area.

Fedora 39 : GNOME new version 44.2 .

The GNOME Project proudly announced today the release and general availability of the GNOME 44 desktop environment series, a major update that brings several new features and lots of improvements.

You can read more on the official website.

You can see a first version 44 on this youtube video:

Fedora 39 : Share folder with Fedora on VirtualBox.

To share a folder called share between the Windows operating system and Fedora 39 using VirtualBox, the folder must be created and added to the settings as follows:

In VirtualBox, make sure the Fedora virtual machine is stopped.

Select the Fedora virtual machine in the list of virtual machines and click the "Settings" button on the top bar of the VirtualBox window.

In the "Settings" window of the virtual machine, select the "Shared Folders" category.

Click the "+" button on the right to add a new shared folder.

In the "Add Share" window, specify the following details:

Folder Path: Browse to and select the C:\share folder on the host.

Folder Name: You can enter a name for the shared folder.

Select the access options you want, such as "Auto-mount" and "Make Permanent".

Click the "OK" button to save the settings.

Start the Fedora virtual machine and on the Fedora virtual machine, open a terminal and run the following command to mount the shared folder:

You can see the file test.txt is visible in Fedora.

Fedora 39 : Regular expressions with gedit editor.

Regular expressions can be used in the gedit editor using the Find and Replace option with the regular expressions checkbox selected. This can be used to remove empty lines from source code, remove comment lines, replace indexing - if using Python scripts, or replace content. Here's an example of how to remove empty lines from a text using regular expressions:

Fedora 39 : Using a stick or hard disk created in Windows.

When attached to USB, Linux distribution cannot access it.

Install these packages with the DNF utility.

sudo dnf install ntfs-3g
sudo dnf install ntfsfix

Use these commands to create a folder where it will be mounted and test if it can be mounted and where it is viewed :

sudo mkdir /mnt/mydrive
sudo mount -t ntfs-3g /dev/sdb1 /mnt/mydrive
dmesg| grep usb 
sudo mount /dev/sdb /mnt/mydrive
df -h

Fix errors with this command

sudo umount /dev/sdb1
sudo ntfsfix /dev/sdb1

It resumes the operation of mounting it in the folder named /mnt/mydrive:

sudo mount -t ntfs-3g /dev/sdb1 /mnt/mydrive

This command will mount as a superuser but can be modified as a normal user.

Create a USB folder into your home folder as normal user.

You can use these commands to use your files like a normal user:

[mythcat@fedora ~]$ sudo mount -t ntfs-3g /dev/sdb1 ~/USB
[sudo] password for mythcat: 
...
[mythcat@fedora ~]$ sudo umount /dev/sdb1

Fedora 39 : The vifm file manager ...

My monitor broke a few days ago so i'm using an old laptop. Website posts will be less frequent.

You can use the vifm file manager in Fedora 39 easy.

Use the DNF command tool to install it.

[root@fedora mythcat]# dnf install vifm

See the result of this file manager:

Fedora 39 : GPT on linux terminal.

The ChatGPT is possible in your Windows, macOS, and Linux terminal ... tgpt is a cross-platform cli (commandline) tool that lets you use ChatGPT 3.5 in Terminal without API KEYS. It communicates with the Backend of Bai chatbot. Its written in Go. You can see the source code on this GitHub project.

Fedora 39 : Fedora 39 Cinnamon environment pre-release - upgrade.

Today I tested the new version of fedora 39 and it worked very well.

If you want to upgrade Fedora using the DNF system upgrade then you can find all information on the official webpage.

You can try a Fedora 39 Cinnamon environment pre-release from this website.

A very good feature comes with this new command remove-retired-packages.

This allow you to keep the all packages with update.

Fedora 38 : LibreOffice with new features.

LibreOffice is a free and powerful office suite, and a successor to OpenOffice.org (commonly known as OpenOffice). Its clean interface and feature-rich tools help you unleash your creativity and enhance your productivity... see the official website.

I install easy with DNF tool on Fedora 38:

[root@fedora mythcat]# dnf install libreoffice.x86_64

Fedora 37 : Lite editor.

lite is a lightweight text editor written mostly in Lua — it aims to provide something practical, pretty, small and fast, implemented as simply as possible; easy to modify and extend, or to use without doing either.

You can find this project on GitHub.

I install with DNF tool:

# dnf install lite-xl.x86_64
...
Installed:
  lite-xl-2.1.1-2.fc38.x86_64

Fedora 37 : SeLinux alert detection from Trend Micro HouseCall.

If you use the tool from Trend Micro HouseCall for Home Networks, then it is possible that the SELinux tool from Fedora Linux will warn you with an alert.

It can be easily fixed with the following commands.

[root@fedora mythcat]# ausearch -c 'journal-offline' --raw | audit2allow -M my-journaloffline
******************** IMPORTANT ***********************
To make this policy package active, execute:

semodule -i my-journaloffline.pp

libsemanage.semanage_get_lock: Could not get direct transaction lock at /var/lib/selinux/targeted/semanage.trans.LOCK. (Resource temporarily unavailable).

Because I got an access error to the resource, I used some Linux commands that checked the status of my selinux, I searched and stopped the process that doesn't let me access the resource and restarted the command:

[root@fedora mythcat]# cat /etc/selinux/config


SELINUX=enforcing
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,

This is how the Selinux alert appears in the environment of the Fedora 37 Linux distribution.

Fedora 37 : Vala development in Fedora 37.

Yesterday I tested the Vala programming language on the Fedora 37 linux distribution. The basic idea was that most linux distribution environments use the GTK+ toolkit that Gnome developed. Development with GTK+ can be done with various programming languages: c, python, rust... The main reason why I tested the implementation of the Vala programming language was that Gnome developed it.

For the installation, I used the DNF utility with the following commands to install the packages necessary for the operation of the development in Vala

$sudo dnf groupinstall "Development Tools" "Development Libraries"
$ sudo dnf install vala

The first command installs the tools that are essential to perform tasks such as installing packages from source code.

The second command only installs the Vala package.

To test the written program we will need to use the Valac compiler and then run it as a simple executable in Linux.

$valac --pkg gtk+-3.0 test.vala 
$ ./test

(test:6198): GLib-GObject-CRITICAL **: 14:34:11.454: g_value_set_boxed: assertion 'G_VALUE_HOLDS_BOXED (value)' failed 

The error is about the implementation of Vala in Fedora, I don't have an answer of this but in other Linux distributions this is not show.

If you want to use WebKit2GTK+ Extensions then you need to compile it.

valac test.vala  --pkg gtk+-3.0 --pkg webkit2gtk-4.0

Is a more easy way to developm application but you need to know well how to deal with GTK and GObject structure.

News: Fedora 37 Beta Available.

The Fedora development team announced the beta for version 37 of the open-source operating system has been released on time on September 13, 2022.

This was announced on Fedora Hyperkitty

If you want to test the new beta of Fedora 37, the default x86_64 version can be downloaded from the official Fedora download server.

You will see this comes with many of changes.

Fedora 37 : Use radiotray-ng to simple radio player.

Radiotray-NG is a simple radio player for Ubuntu that runs from the system tray.

You can use this command to install the package.

dnf install radiotray-ng

After installation, you will see an icon on the tray area.

Use this to select the radio and this will play it.

The project can be found on GitHub.

Fedora 37 : Starting with the conda tool.

In this tutorial, I will show the first steps for working with conda tool on Fedora 37.

Conda is an open-source package management system and environment management system that runs on Windows, macOS, Linux, and z/OS. Conda quickly installs, runs, and updates packages and their dependencies. Conda easily creates, saves, loads, and switches between environments on your local computer. It was created for Python programs, but it can package and distribute software for any language., see the official webpage.

I used the DNF tool to install this tool.

[root@fedora mythcat]# dnf install conda

By default, Conda is configured to activate the base environment when I open a fresh terminal session and you can set it to false.

[mythcat@fedora ~]$ conda config --set auto_activate_base false

For the changes to be applied, run the source command with the .bashrc file as an argument.

[mythcat@fedora ~]$ source ~/.bashrc

After installation, the conda can be activated with the base environment.

[mythcat@fedora ~]$ conda activate
(base) [mythcat@fedora ~]$ conda deactivate
[mythcat@fedora ~]$

Let's start a new project environment named test001 with this command:

[mythcat@fedora ~]$ conda create -n test001 python=3.9
...
  zlib               pkgs/main/linux-64::zlib-1.2.12-h5eee18b_3

#
# To activate this environment, use
#
#     $ conda activate test001
#
# To deactivate an active environment, use
#
#     $ conda deactivate

The next step is to activate this with the next command and list installed packages in a conda environment.

[mythcat@fedora ~]$ conda activate test001
(test001) [mythcat@fedora ~]$ conda list

If you want to see all environments then use the next command:

(test001) [mythcat@fedora ~]$ conda env list
# conda environments:
#
test001               *  /home/mythcat/.conda/envs/test001
base                     /usr

The basic usage of conda is to install packages, you can see how to install the scipy package with the next command:

(test001) [mythcat@fedora ~]$ conda install scipy

Using the conda tool.

Also, you can update a package like the pip tool, see the next command:

(test001) [mythcat@fedora ~]$ conda update
CondaValueError: no package names supplied
# Example: conda update -n myenv scipy 

You can deactivate/deactivate the environment with these commands:

(test001) [mythcat@fedora ~]$ conda deactivate
[mythcat@fedora ~]$ conda activate test001
(test001) [mythcat@fedora ~]$ 

You can export the conda environment into YML file type:

(test001) [mythcat@fedora ~]$ conda env export > test001.yml
(test001) [mythcat@fedora ~]$ ls test001.yml
test001.yml 

With this file, you can create a new environment in another area, and see the next commands for deactivating and creating the new environment.

(test001) [mythcat@fedora ~]$ conda deactivate
[mythcat@fedora ~]$ ls
Desktop    Downloads     Music     Public     test001.yml
Documents  kernel-tests  Pictures  Templates  Videos
[mythcat@fedora ~]$ conda env create -f test001.yml
CondaValueError: prefix already exists: /home/mythcat/.conda/envs/test001

Because I try to create in the same place as the old environment I got this error.

You need to use the YML file in another place.

Another option is to clone one environment.

[mythcat@fedora ~]$ conda create --name test001_new_clone --clone test001
Source:      /home/mythcat/.conda/envs/test001
Destination: /home/mythcat/.conda/envs/test001_new_clone
Packages: 34
...

You can see all environments with this command:

[mythcat@fedora ~]$ conda info --env
# conda environments:
#
test001                  /home/mythcat/.conda/envs/test001
test001_new_clone        /home/mythcat/.conda/envs/test001_new_clone
base                  *  /usr

These commands shown are just the beginning of working with the conda utility. It has many more development options.

Fedora 37 : Kernel Test Days.

The main goal of a Kernel Test Day is to test a new kernel on many different machines as possible ...

To test the kernel and help the Fedora development team you need to run one tool from Fedora.

I used DNF to install the fedora python package.

[root@fedora kernel-tests]# dnf install python3-fedora.noarch
...
Installed:
  python3-fedora-1.1.1-7.fc37.noarch                                            
  python3-kitchen-1.2.6-14.fc37.noarch                                          
  python3-lockfile-1:0.12.2-8.fc37.noarch                                       
  python3-munch-2.5.0-10.fc37.noarch                                            
  python3-openidc-client-0.6.0-17.20220119git0e2ed81.fc37.noarch                

Complete!

I install the Development Tools group for development issues.

[mythcat@fedora kernel-tests]$ sudo dnf -y groupinstall "Development Tools"

I clone the kernel-tests tool from the GitHub repository.

[mythcat@fedora ~]$ git clone https://pagure.io/kernel-tests.git
Cloning into 'kernel-tests'...

Into the folder kernel-tests set your user and password to send data to the Fedora development team.

[mythcat@fedora ~]$ cd kernel-tests/
[mythcat@fedora kernel-tests]$ cp config.example .config
[mythcat@fedora kernel-tests]$ vi .config

Set the SELinux settings, if this is enabled.

[mythcat@fedora kernel-tests]$ sudo semanage boolean -m --on selinuxuser_execheap

I run both tests, like in the documentation area.

See these results of my tests on HP Compaq 6710b laptop:

Fedora 37 : Install PyQt5 and PyQt6 on Fedora.

In this tutorial, I will show you how to install PyQt5 and PyQt6 on Fedora 37 Distro Linux.

I used the DNF tool on the sudo user.

To install PyQt5 I used this command:

[root@fedora mythcat]# dnf install python3-qt5.x86_64
Last metadata expiration check: 2:20:40 ago on Wed 17 Aug 2022 09:42:57 PM EEST.

If you want to use PyQt6 then you need to use the sip solution.

Let's search and install it with the DNF tool.

[root@fedora mythcat]# dnf search qt6 | grep python

Complete!

I used the python command and I import PyQt5 and PyQt6

[mythcat@fedora ~]$ python
Python 3.11.0rc1 (main, Aug  9 2022, 00:00:00) [GCC 12.1.1 20220810 (Red Hat 12.1.1-4)] on linux

The python modules are installed and working well.

Fedora 37 : About DNF tool.

DNF's name tool comes from Dandified YUM.

You can find all about this tool in the Fedora documentation area.

As you know the YUM is in use on older systems and comes from Yellowdog Updater, Modified.

All of these tools need to have sudo that gives you administrative access to your system.

When you run the DNF tool this will checks for metadata automatically whenever you begin a system update or otherwise install software from repositories.

For this reason, the update and upgrade commands perform the same function.

Let's see the basic usage of the DNF tool:

Search a fedora package named FedoraPackage in the repositories.

sudo dnf search FedoraPackage

Install the FedoraPackage package if exist in the repository.

sudo dnf install FedoraPackage

If you want to uninstall the package FedoraPackage use this:

sudo dnf remove FedoraPackage

I can reinstall the package FedoraPackage

sudo dnf reinstall FedoraPackage -y

To automatically remove unneeded dependencies, use:

sudo dnf autoremove

The DNF can find out which package provides a particular file.

sudo dnf provides /etc/httpd/conf/httpd.conf

The detailed information of a package can be viewed with:

sudo dnf info httpd

The DNF history contains all actions that have been performed by the DNF command.

sudo dnf history

I can view further information about a transaction by specifying its ID:

sudo  dnf history info 13

I can undo this transaction if we want:

sudo dnf history undo 13 -y

I can redo with:

sudo dnf history redo 13 -y

The DNF will cache data to the /var/cache/dnf directory and I clean it with:

dnf clean all

I have the option to manually make the cache so that future actions will be quicker.

sudo time dnf makecache

The DNF tool gives me the ability to list all packages that are currently installed on our Linux system:

sudo dnf list installed

Packages that are related to each other may be grouped together into a package group.

sudo dnf grouplist

I can install it with this command:

sudo dnf groupinstall "Web Server" -y

I can check if an update is available

sudo dnf check-update

I can ignore an update for the FedoraPackage package with this command:

sudo dnf update -x FedoraPackage

I can use it for automatic tasks such as updating regularly via cron jobs.

sudo  dnf install dnf-automatic -y

I can install security only

sudo dnf updateinfo list sec

I can see displays information for enabled repositories only:

sudo dnf repolist

I can see all of the repositories

sudo dnf repolist all

Set update testing with:

sudo dnf config-manager --set-enable updates-testing

Disable update testing:

sudo dnf config-manager --set-disable updates-testing

You can list packages from a specified repository, for instance, FedoraPackage:

sudo dnf repository-packages FedoraPackage list

To display only a list of those packages available from the specified repository, add the available option.

sudo dnf repository-packages fedora list available

To display only a list of those packages installed from the specified repository, add the installed option

sudo dnf repository-packages fedora list installed

To add and enable a new repository like Grafana, run the following command.

Open a new file named grafana.repo:

sudo nano /etc/yum.repos.d/grafana.repo

Add this in the grafana.repo

[grafana]
name=grafana
baseurl=https://packages.grafana.com/oss/rpm
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packages.grafana.com/gpg.key
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

sudo dnf config-manager --add-repo /etc/yum.repos.d/grafana.repo

To enable the DNF repository

sudo dnf --enablerepo=grafana install grafana

To disable a DNF repository

sudo dnf --disablerepo=fedora-extras install grafana 

To permanently disable a particular repository

sudo dnf config-manager --set-disabled grafana

These are just a few basic ways to use the DNF utility.

Fedora 37 : First test with the Fedora Cinnamon spin.

The Fedora Cinnamon spin provides advanced innovative features and a traditional user experience.

I install this Fedora Spin from the official website.

I installed it again without an update.

It seemed faster than the old distro 36 with the Mate environment.

Here is a screenshot of Fedora 37 on the HP C6710b laptop. 

Fedora 36 : Rootkit Hunter tool.

rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. It does this by comparing SHA-1 hashes of important files with known good ones in online databases, searching for default directories (of rootkits), wrong permissions, hidden files, suspicious strings in kernel modules, and special tests for Linux and FreeBSD..., see wikipedia .

You can find it on this website.

On Fedora 36 you can search and install with the DNF tool.

[root@fedora mythcat]# dnf search rkhunter
Last metadata expiration check: 3:38:34 ago on Sat 06 Aug 2022 10:35:34 AM EEST.
======================== Name Exactly Matched: rkhunter ========================
rkhunter.noarch : A host-based tool to scan for rootkits, backdoors and local exploits
[root@fedora mythcat]# dnf install rkhunter.noarch
Last metadata expiration check: 3:39:00 ago on Sat 06 Aug 2022 10:35:34 AM EEST.

The first step is to upgrade it and then you can check the system.

[root@fedora mythcat]# rkhunter --propupd
[ Rootkit Hunter version 1.4.6 ]
File created: searched for 179 files, found 139

[root@fedora mythcat]# rkhunter --check
[ Rootkit Hunter version 1.4.6 ]

Checking system commands...

  Performing 'strings' command checks

...

The result can be found on the log file and you can set settings on the conf file type.

[root@fedora mythcat]# vi /var/log/rkhunter/rkhunter.log
[root@fedora mythcat]# vi /etc/rkhunter.conf

Fedora 36 : first steps with the Hy.

Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.

This is quite similar to the old GIMP Script Fu that I've worked with in the past. The syntax assumes a join like tabs in HTML, only we'll use parentheses. I haven't studied in detail the implications it has with the python language, but it certainly wasn't invented for nothing.

First, you need to install it with the pip tool.

[mythcat@fedora ~]$ pip3 install hy --user
Collecting hy
...
Successfully built hy
Installing collected packages: funcparserlib, colorama, hy
Successfully installed colorama-0.4.5 funcparserlib-1.0.0 hy-0.24.0

The I test some examples:

[mythcat@fedora ~]$ hy
Hy 0.24.0 using CPython(main) 3.10.5 on Linux
=> (setv a 1)
=> "hello world"
"hello world"
=> (setv mylist [1 2 3])

=> (get mylist 0)
1
=> (defn greet [name]
...  "Hello "
...  (print "Hello " name))
=> (greet "mythcat")
Hello  mythcat

You can test it online with this online tool:

Fedora 36 : The zeek tool.

Zeek is a powerful network analysis framework that is much different from the typical IDS you may know.

Use the DNF tool to add repo for zeek tool:

[root@fedora home]# dnf config-manager --add-repo https://download.opensuse.org/repositories/security:zeek/Fedora_36/security:zeek.repo

Adding repo from: https://download.opensuse.org/repositories/security:zeek/Fedora_36/security:zeek.repo

Use DNF tool to install

[root@fedora home]# dnf install zeek-lts

Fedora 36 : Fill out this survey for a badge.

I've always liked Fedora distro because it applies a concept of interactivity between developers and users.

Even if not everything works, you can see the progress made from the older versions.

Today I completed my feedback in a survey requested by them and I also got a small badget for my effort.

You can find it on this webpage.

Fedora 36 : Inkscape 1.2 with Huion WH 1409 graphic tablet.

In this tutorial I will show you how to install and use the Huion WH 1409 graphics tablet with the new release of Inkscape 1.2 software.

You will need to use the DKMS feature of the kernel and the tablet-specific drivers.

Let's start with the following command to get the driver and show the files:

[root@fedora mythcat]# git clone https://github.com/DIGImend/digimend-kernel-drivers.git

digimend-debug    hid-rebind        hid-viewsonic.c
dkms.conf    hid-uclogic-core.c  Makefile

Let's create it using the command

[root@fedora digimend-kernel-drivers]# make dkms_install
...

dkms add .
Creating symlink /var/lib/dkms/digimend/11/source -> /usr/src/digimend-11
dkms build digimend/11

Building module:
cleaning build area...
make -j1 KERNELRELEASE=5.17.9-300.fc36.x86_64 KVERSION=5.17.9-300.fc36.x86_64...
...

Let's check and reboot.

[root@fedora digimend-kernel-drivers]# dkms status
digimend/11, 5.17.9-300.fc36.x86_64, x86_64: installed (original_module exists)
[root@fedora digimend-kernel-drivers]# reboot

After rebooting the diver must be activated and you will see that Linux responds to the movement of the tablet pen.

[root@fedora mythcat]# modprobe -r hid-kye hid-uclogic hid-viewsonic

Install the latest version of inkscape 1.2 using the DNF utility.

Start the inkscape software:

[mythcat@fedora ~]$ inkscape
static bool Inkscape::UI::Dialog::DialogContainer::recreate_dialogs_from_state(InkscapeWindow*, const Glib::KeyFile*): Key
file does not have group “Windows”
Gdk-Message: 15:09:10.534: Error flushing display: Broken pipe

It seems that inkscape does not detect and set the tablet if you use the settings of this software, but you can use the tablet with this software even if you do not set it.

Fedora 36 : Install django-hypergen and test it.

Today I test the last version of python version 3.11.0a7 with the Django-hypergen example.

The install process can be found on the GitHub page project.

You can see the full tutorial here.

News: Firefox 100 on Fedora distro.

This new release can download it and read more on the official webpage.

I tested today and as you can see this is working well:

Fedora 36 : Use the ykman tool - part 001.

You can see a full tutorial about how can install this linux tool for yubikey device on this tutorial.

The next command will program a random 38 character long static password to slot 1 on the device:

# ykman otp static 1 --generate --length 38 --force --keyboard-layout US

News: Fedora 36 beta released.

Fedora 36 beta was released and I tested it today.

First of all, Fedora 36 is still in pre-release mode and you should be careful to back up your data before upgrading it has a rollback option just in case.

I haven't seen any significant differences in browsing, and overall it seems faster.

The upgrade commands are the same but the installation process seems more complex.

# dnf upgrade --refresh
# dnf autoremove
# dnf install dnf-plugin-system-upgrade -y
# dnf system-upgrade download --releasever=36 --allowerasing
# dnf system-upgrade reboot
# cat /etc/os-release 

Let's fix the install process:

# dnf system-upgrade clean
# symlinks -r -d /usr 

This is ascreenshot take on my HP Compaq 6710b laptop, you can see the Workstation Edition Prerelease.

Fedora 35 : Kdenlive tool.

Note:

The new title of this blog is:About Fedora Linux distro

This was my first blog since blogspot.com and now blogger.com and I wrote my first articles and tutorials using the Linux operating system, especially Fedora distro.

Because I used it so much and it had an impact on my free time. Initially the title was generic "About me and my life" and I later kept it for S.E.O. and because it worked just as well as me.

The new title will not change the content at all and I hope it will come with new and good content.

---

Let's go back to today's tutorial article: installing kdenlive software.

Kdenlive is a powerful free and open source cross-platform video editing program made by the KDE community.

The last release was on Jan 7, 2022.

I use the DNF utility as follows:

[root@fedora mythcat]# dnf search kdenlive

...
Complete!

After install I run well with this software:

[mythcat@fedora ~]$ kdenlive

Fedora 35 : Testing the new Django web framework version 4.0.1 with channels.

Today I tested in Fedora 35 the new version 4.0.1 of the Django framework and the channels package.

Channels augments Django to bring WebSocket, long-poll HTTP, task offloading, and other async support to your code, using familiar Django design patterns and a flexible underlying framework that lets you not only customize behaviors but also write support for your own protocols and needs. see the GitHub website.

The entire tutorial can be viewed on my blog about python programming language.

The result shows that it works with the admin webpage:

Fedora 35 : Roblox Player and Roblox Studio with Grapejuice.

In today's tutorial, I will show you how to install and play Roblox on the Linux Fedora 35 distribution using Grapejuice software.

The Grapejuice software installs protocol handlers to open games from the Roblox website and file handlers to open place files. It also provides a management interface for installing and launching Roblox.

For this, you will need to have a computer with the necessary hardware requirements for this online game.

I tested it on the old HP Compaq 6710b laptop on which I installed Fedora version 35 and it worked very hard.

Here are the Linux commands I used to install.

Fedora 35 : OBS Studio tool.

This is a free and open-source software for video recording and live streaming for Linux, Mac, and Windows.

You can download it from the official webpage.

This software can be install with the DNF tool:

If you have an old laptop with an old graphic card then this software will not work.

Fedora 35 : New Krita version 5.0.0 released.

Today I tested the new released version 5.0.0 for Krita software.

I download the AppImage from the official website.

After download you need to use these commands:

[mythcat@fedora ~]$ chmod +x krita-5.0.0-x86_64.appimage
[mythcat@fedora ~]$ ./krita-5.0.0-x86_64.appimage

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Old schema: "0.0.10" New schema: 0.0.15

The Krita software runs well on the old HP Compaq 6710b, but I recommend better hardware because it is a software for graphic activities.

Don't worry about the message is a database change warning message.

Fedora 35 : Python and Flask-Mailing on Fedora.

First of all, a Merry Christmas to the users and the Fedora team. Python version 3.10.1 works very well on Fedore 35 and today I tested a packet called: Flask_Mailing.

Flask-Mailing adds SMTP mail sending to your Flask applications., see the Github repo.

Let's start with the installation of this packet with the pip utility.

[mythcat@fedora ~]$ pip install -U flask-mailing
Defaulting to user installation because normal site-packages is not writeable
Collecting flask-mailing
  Downloading Flask_Mailing-0.0.5-py3-none-any.whl (15 kB)

I create a folder named ExempleFlask001:

[mythcat@fedora ~]$ mkdir ExempleFlask001
[mythcat@fedora ~]$ cd ExempleFlask001/
[mythcat@fedora ExempleFlask001]$ vi flask001.py

I created the simplest example to test through the import procedure and then read with the dir function, here is the source code:

from flask import Flask
from flask_mailing import Mail, Message

app = Flask(__name__)
@app.route("/")
def index():
    test = str(dir(Mail))
    return test
if __name__ == "__main__":
    app.run(debug=True)

The result of running the script on the command line:

[mythcat@fedora ExempleFlask001]$ python flask001.py
 * Serving Flask app 'flask001' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.

The browser's response to the script is this:

Fedora 35 : Share your commands online with asciinema tool on blogger.com .

The asciinema.org is now running the latest server and web player code and thus it fully supports this new format.

In the last tutorial about this online tool we briefly presented how it can be used.

In this tutorial, I will present some other features and how you can integrate the result in blogger.com.

Let's see a short example with some simple commands in Linux and how we used this tool:

[mythcat@fedora ~]$ asciinema auth
[mythcat@fedora ~]$ asciinema rec linux_commands_default.cast
asciinema: recording asciicast to linux_commands_default.cast
asciinema: press <ctrl-d> or type "exit" when you're done
[mythcat@fedora ~]$ ls
...
[mythcat@fedora ~]$ dir
...
[mythcat@fedora ~]$ pwd
...
[mythcat@fedora ~]$
exit
asciinema: recording finished
asciinema: asciicast saved to linux_commands_default.cast
[mythcat@fedora ~]$ asciinema upload linux_commands_default.cast

I used the local recording and uploaded it later to avoid additional fixes in case of errors and inconsistencies with what we want to display online.

The asciinema online tool supports sharing an asciicast on Twitter, Slack, Facebook, Google+, or any other site which supports one of these APIs: oEmbed, Open Graph, and Twitter Card APIs, see also this webpage.

To use this online tool with your blog, you will need to use the three lines of source code to change according to the number of asciinema uploaded from the URL.

In my example case is this number 455414 from this URL: https://asciinema.org/a/455414/ and the source code for this blog post is shown below:

<script src="https://github.com/asciinema/asciinema-player/releases/download/v2.6.1/asciinema-player.css"/></script>
<script src="https://github.com/asciinema/asciinema-player/releases/download/v2.6.1/asciinema-player.js"/></script>
<script id="asciicast-455414" src="https://asciinema.org/a/455414.js" async></script>

Here is the result of the source code above, it did not work now because I don't add javascript libraries on the script area.
