Fedora : Fedora SilverBlue 44 and distrobox tool.

Distrobox on Fedora is a lightweight, rootless way to run any Linux distribution inside a tightly‑integrated container, powered by Podman. It’s more flexible than Fedora’s native Toolbox because it can pull any OCI image (Ubuntu, Arch, Debian, openSUSE, Alpine, etc.)

What Distrobox Does on Fedora

• Runs any distro inside your terminal using Podman or Docker.
• Integrates with the host: shared $HOME, USB devices, audio, GUI apps (X11/Wayland).
• No root needed — perfect for immutable Fedora variants like Silverblue/Kinoite.
• Exports apps from the container back to Fedora using distrobox-export.

Install Distrobox on Silverblue

rpm-ostree install distrobox
systemctl reboot

Create and enter a Gentoo container

distrobox create -i gentoo/stage3:latest -n gentoo
distrobox enter gentoo

Sync and update Gentoo

emerge --sync
emerge --ask --update --deep --newuse @world
...

Gentoo inside Distrobox is source‑based, this means:

Compiling packages happens inside the container

CPU and RAM usage will be high

Builds may take a long time (depending on your hardware)

Silverblue’s immutability does not affect Gentoo’s compilation.

Fedora : Fedora SilverBlue 44 on VirtualBox 7.2.10 - first commands to start .

Fedora Silverblue is an immutable desktop operating system built on top of rpm‑ostree. Instead of traditional package-based upgrades, Silverblue uses atomic deployments, making the system extremely stable, reliable, and easy to roll back. This blog-style guide shows you how to update your system, manage deployments, upgrade to new Fedora versions, and keep Flatpak applications current — all using simple terminal commands. Tested on VirtualBox.

Check your current system state

Before updating, it is useful to inspect your current deployment and any layered packages.

rpm-ostree status

Most apps in Silverblue come from Flatpak.

sudo su
flatpak update

Perform a standard system update

This updates your Silverblue installation to the latest available deployment for your current Fedora release.

sudo rpm-ostree upgrade
systemctl reboot

Clean up old deployments

Silverblue keeps multiple system deployments so you can roll back if needed. You can safely clean older ones to free space and reduce clutter.

rpm-ostree status
sudo rpm-ostree cleanup -p
sudo rpm-ostree cleanup -m

Roll back if something breaks

If an update causes issues, you can revert to the previous deployment quickly and safely.

rpm-ostree status
sudo rpm-ostree rollback
systemctl reboot

Rebase to a new Fedora Silverblue version

Major upgrades are done via rebase. Replace 41 with your target Fedora version. I used Fedora 44 and I keep that version.

rpm-ostree status
sudo rpm-ostree rebase fedora:fedora/41/x86_64/silverblue
systemctl reboot

Manage layered RPM packages

Although Silverblue is immutable, you can still layer RPM packages on top of the base image. Here is how to inspect and remove them.

rpm-ostree status
sudo rpm-ostree uninstall package-name
systemctl reboot

Troubleshooting tips

If updates fail or downloads hang, you can refresh metadata or inspect rpm-ostree logs.

sudo rpm-ostree refresh-md
journalctl -u rpm-ostreed

News : start translation updates was due to the migration on Fedora

Updates to translations of Fedora Documentation are again available. As announced on March 3rd, the unavailability of translation updates was due to the migration of the translation repositories and necessary tools from Pagure to the Fedora Forge. It took longer than expected but we are pleased to report this undertaking came finally to the end.
