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.

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.
