Fedora Silverblue is a robust, atomic desktop operating system that shines for daily use, development, and container-based workflows. Its standout feature is the ability to roll back changes easily, making upgrades like rebasing to Fedora Linux 44 a breeze. Whether you prefer a graphical interface or the command line, this guide will walk you through each step—and show you how to revert if anything goes wrong. Let’s dive into the seven essential steps.
1. Update Your Existing System First
Before rebasing to Fedora Linux 44, ensure your current Silverblue installation is fully up to date. This prevents conflicts and ensures a smooth transition. Open a terminal and run rpm-ostree update to apply any pending updates. Alternatively, you can update through GNOME Software and reboot afterward. Remember, rpm-ostree is the underlying atomic technology for all Fedora Atomic Desktops, so these commands apply across variants like Kinoite or Sericea with appropriate adjustments.
2. Verify the New Release Is Available
Once updated, check if the Fedora Linux 44 branch is ready for your system. In the terminal, type ostree remote refs fedora. Look for an entry like fedora:fedora/44/x86_64/silverblue. If you see it, you're good to go. This step confirms that the rebase target exists and matches your architecture. For users of other desktop spins, substitute silverblue with the appropriate name (e.g., kinoite for KDE).
3. Pin Your Current Deployment (Optional but Recommended)
To keep your existing system as a fallback option in the boot menu, pin the deployment. Run sudo ostree admin pin 0 (where 0 is the entry position shown in rpm-ostree status). This ensures you can always revert temporarily. If you later change your mind, unpin with sudo ostree admin pin --unpin 2 (adjust the number). Pinning is a safety net—use it if you're cautious about the upgrade.
4. Rebase Using GNOME Software (GUI Method)
If you prefer a graphical approach, open GNOME Software and navigate to the Updates screen. You’ll see a notification about Fedora Linux 44’s availability. Click Download to fetch the new image—this may take a while. Once downloaded, a Restart & Upgrade button appears. Click it, and your system will reboot into the upgraded environment. That’s all there is to it! This method is perfect for users who want a hassle-free experience.
5. Rebase Using the Terminal (CLI Method)
For command-line enthusiasts, rebasing via terminal is straightforward. First, ensure the branch is available (as in step 2). Then execute rpm-ostree rebase fedora:fedora/44/x86_64/silverblue. This command switches your system to the new version. Finally, reboot with sudo reboot. After restart, you’ll be running Fedora Linux 44. The terminal method gives you more control and is ideal for scripting or automation.
6. Reboot and Enjoy Fedora Linux 44
After rebooting—whether via GUI or CLI—your system will boot into Fedora Linux 44. On the first boot, you may notice a brief setup process as the new deployment finalizes. Check the version with hostnamectl or rpm-ostree status to confirm you’re on the 44 branch. Explore new features and enjoy the latest updates. If everything works smoothly, you’re all set.
7. Roll Back If Something Goes Wrong
Encounter issues? No problem. At GRUB boot menu, select the previous deployment (the one you pinned or the default old version). If GRUB isn’t visible, press ESC during boot. To make the rollback permanent, run rpm-ostree rollback after logging into the older system. This resets your default to that deployment. You can always reattempt the rebase later after troubleshooting.
Rebasing Fedora Silverblue to version 44 is a safe process, thanks to atomic updates and rollback capabilities. Whether you choose the GUI or terminal, you now have a clear roadmap. Enjoy your upgraded system!
