PSA, the @fedora #Incus and LXC images are about to disappear from our image servers. This is because it's been 10 days since we last were able to build them. Looking into it, now it appears that Fedora has deployed Anubis on kojipkgs.fedoraproject.org which is the site we're using to download the OCI artifacts acting as the base image.

I've reached out now to the Koji folks to try and get either another location we can pull those from, or some kind of exception, but this may still lead to a few days without Fedora images available.
