Pulling manifest: ostree-image-signed:docker://ghcr.io/ublue-os/aurora-dx:stable-daily
error: Preparing import: Fetching manifest: failed to invoke method OpenImage: A signature was required, but no signature exists
Looks like a signature problem with the stable-daily image. I’d switch over to stable until it’s fixed.
Unfortunately this can happen if something goes wrong with the signing stage of the build process. There is also a small issue with build pipeline that makes this possible, plan is to fix that too in the near future.
And we currently cannot build just the daily image separately from the normal stable (when building manually).
We will do a new stable build to fix the copy.fail CVE tonight once CoreOS has done their release, should then fix the daily image too.
