Could anyone help me resolve this error?

Pulling manifest: ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-deck:42.20251019
error: Preparing import: Fetching manifest: failed to invoke method OpenImage: reading manifest 42.20251019 in ghcr.io/ublue-os/bazzite-deck: manifest unknown
System update failed:
0: Command failed: /usr/bin/rpm-ostree upgrade
1: /usr/bin/rpm-ostree failed: exit status: 1

Anyone know of I should post this elsewhere to try and get assistance on a resolution?

:white_check_mark: How to Fix the “manifest unknown” Error on Bazzite (rpm‑ostree)

You’re seeing this error because your system is trying to update to an image tag that no longer exists on GitHub Container Registry (GHCR). Bazzite regularly rotates old tags, and when a tag disappears, rpm‑ostree can no longer fetch the manifest.

This is why you get:

Kod

manifest unknown
System update failed:
Command failed: /usr/bin/rpm-ostree upgrade

:check_mark: Solution: Rebase to a valid, current image

Run this command:

Kod

sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bazzite-deck:stable

This will:

  • Point your system to the current stable Bazzite image

  • Download a valid manifest

  • Create a new deployment that rpm‑ostree can actually update

Then reboot:

Kod

sudo systemctl reboot

:memo: Notes

  • This issue happens when the system is pinned to an old or removed tag.

  • Rebasing to stable is the recommended fix from the Bazzite team.

  • If you still get errors after rebasing, share the output of:

Kod

rpm-ostree status
