#4 [1/4] FROM docker.io/library/centos:8.1.1911@sha256:fe8d824220415eed5477...
#4 DONE 0.0s

#5 [2/4] RUN dnf -y update
#5 CACHED


Looks like in the main repo, it is using cached container layer for
the "dnf -y update" command, and so not pulling in the new centos-release
package.

In forks where the cache is not valid, it'll really run the "dnf update"
command and see the failure.

I think if you go to

  https://gitlab.com/qemu-project/qemu/container_registry

and delete the currently cached centos8 image, then all subsequent runs
will fail until this patch is merged.

Daniel
