Fedora Silverblue: Rebasing to Fedora Linux 44 – Questions & Answers

Welcome to this comprehensive Q&A guide on rebasing your Fedora Silverblue system to the latest Fedora Linux 44 release. Whether you're a seasoned user or new to Silverblue, this format breaks down the process into clear, manageable steps. We'll cover pre-update checks, both graphical and terminal methods, and how to safely revert if needed. Each question links to related sections for easy navigation. Let's dive in!

1. What should I do before rebasing my Fedora Silverblue system?

Before starting the rebase, it's critical to apply all pending updates to your current system. This ensures a smooth transition. Open a terminal and run rpm-ostree update or use GNOME Software to install any available updates. After updating, reboot your system. This step prevents conflicts that might arise from outdated packages during the rebase process. Remember, rpm-ostree is the atomic update engine underlying all Fedora Atomic Desktops, so similar procedures apply to other spins with minor adjustments.

2. How do I rebase to Fedora Linux 44 using GNOME Software?

GNOME Software makes rebasing visually straightforward. Navigate to the Updates screen, where you'll see a notification about the availability of Fedora Linux 44. Click the Download button to fetch the new image—this may take some time depending on your internet speed. Once the download completes, the update status changes to “Ready to install.” Click Restart & Upgrade. Your system will apply the update and reboot automatically, leaving you with a shiny new Fedora Linux 44 installation. That's all there is to it!

3. How do I rebase using the terminal?

For terminal enthusiasts, rebasing is equally simple. First, verify that the Fedora 44 branch is available by entering ostree remote refs fedora in your terminal. Look for a line like fedora:fedora/44/x86_64/silverblue. Next, (optional) pin your current deployment to keep it in GRUB for easy rollback: sudo ostree admin pin 0 (replace 0 with the deployment index from rpm-ostree status). Then rebase with rpm-ostree rebase fedora:fedora/44/x86_64/silverblue. Finally, reboot your computer and boot into Fedora Linux 44. That's it!

4. Can I pin my current deployment before rebasing?

Absolutely. Pinning a deployment ensures it remains available in the GRUB boot menu until you decide to remove it. To pin, first check your deployments with rpm-ostree status—the current booted entry is usually index 0. Then run sudo ostree admin pin 0. Later, if you want to unpin, use sudo ostree admin pin --unpin 2 (adjust the index as needed). Pinning is a safety net: if the new rebase gives you trouble, you can easily roll back to the pinned version.

5. How do I roll back if something goes wrong after rebasing?

If you encounter issues booting into Fedora Linux 44, recovery is painless. During startup, watch for the GRUB menu—press ESC repeatedly if it doesn't appear automatically. Select the entry corresponding to your previous Fedora version (e.g., Fedora 43). Your system will boot into that older deployment. To make this change permanent, log in and run rpm-ostree rollback. This command sets the previous deployment as the default. You can also use the pinning feature to keep multiple versions for testing.

6. Is rebasing via GNOME Software different from using the terminal?

Under the hood, both methods achieve the same result—they download and deploy a new atomic image. GNOME Software provides a user-friendly interface with progress bars and notifications, ideal for those less comfortable with command-line tools. The terminal method offers finer control, such as pinning deployments or verifying branch availability before proceeding. Choose whichever fits your workflow. Regardless of the method, always update your system first and be prepared to roll back if needed.
