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. Let’s see the steps to upgrade to the newly released Fedora 37 Beta, and how to revert if anything unforeseen happens.
Before attempting an upgrade to the Fedora 37 Beta, apply any pending upgrades.
Updating using terminal
Because the Fedora 37 Beta is not available in GNOME Software, the whole upgrade must be done through a terminal.
First, check if the 37 branch is available, which should be true now:
$ ostree remote refs fedora
You should see the following line in the output:
If you want to pin the current deployment (this deployment will stay as option in GRUB until you remove it), you can do it by running:
# 0 is entry position in rpm-ostree status $ sudo ostree admin pin 0
To remove the pinned deployment use following command (2 corresponds to the entry position in
$ sudo ostree admin pin --unpin 2
Next, rebase your system to the Fedora 37 branch.
$ rpm-ostree rebase fedora:fedora/37/x86_64/silverblue
Finally, the last thing to do is restart your computer and boot to Fedora Silverblue 37 Beta.
How to revert
If anything bad happens — for instance, if you can’t boot to Fedora Silverblue 37 Beta at all — it’s easy to go back. Pick the previous entry in the GRUB boot menu (you need to press ESC during boot sequence to see the GRUB menu in newer versions of Fedora Silverblue), 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 37 Beta and back. So why not do it today?
