Rebasing on signed Universal Blue images

First, install an unsigned image:

rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/bluefin:39

Enroll the secure boot key:

ujust enroll-secure-boot-key

Reboot and install the MOK key.

Now you should be able to rebase to the signed image using

rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bluefin:39
