Silverblue is an operating system for your desktop built on Fedora Linux. It’s excellent for daily use, development, and container-based workflows. It offers numerous advantages such as being able to roll back in case of any problems. If you want to update to F34 Beta on your Silverblue system, this article tells you how. It not only shows you what to do, but also how to revert back if anything unforeseen happens.
Prior to the update to Fedora 34 Beta, apply any pending upgrades.
Updating using terminal
Because the Fedora 34 Beta is not available in GNOME Software, the whole upgrade must be done through terminal.
First, check if the 34 branch is available, which should be true now:
$ ostree remote refs fedora
You should see the following line in the output:
Next, rebase your system to the Fedora 34 branch.
$ rpm-ostree rebase fedora:fedora/34/x86_64/silverblue
Finally, the last thing to do is restart your computer and boot to Fedora Silverblue 34 Beta.
How to revert
If anything bad happens — for instance, if you can’t boot to Fedora Silverblue 34 Beta at all — it’s easy to go back. Pick the previous entry in the GRUB boot menu, and your system will start in its previous state. To make this change permanent, use the following command:
$ rpm-ostree rollback
That’s it. Now you know how to rebase to Fedora Silverblue 34 Beta and back. So why not do it today?
