rpm-ostree status and what version does it return?
rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-gnome:stable to update. Before you do that though it's probably worth pinning your current image with sudo ostree admin pin 0 Just incase, you want to be able to keep booting what you currently have installedstable ghcr.io/ublue-os/bazzite-gnome part of the image url in rpm-ostree status and paste that into a browser then you can see all the tags available to rebase to. there is probably a better way to do it

skopeo list-tags docker://ghcr.io/ublue-os/bazzite-gnome
