Comment 10 for bug 1959524

I've investigated this particular error which is different that the one reported originally. So the issue in this case (as we had previously) it's appstream and baseos repos being out of sync because they are picking different mirrors.

This shouldn't happen if we use AFS mirrors for the mirrors as they sync from the same source repo server, but in this case we are including both the repos config with AFS mirrors and the default ones using mirrorlist:

CentOS should provide some way to avoid this kind of issues but there is not a solution from their side yet.

I'd say we should ensure we are only using the AFS ones for all centos repos, i think that's our best bet so far.
