Hello! I tried to install "python2-koji-hub-plugins" package from epel-7 repository, but it failed with the following error: Problem 1: conflicting requests - nothing provides python2-qpid-proton needed by python2-koji-hub-plugins-1.21.1-1.el7.noarch "python2-qpid-proton" exists in epel aarch64 repository, but not in x86_64 repository.
This is due to qpid-proton in epel7 moving to python3, but koji not. At this point I would stongly advise you to not deploy any koji hubs with epel7. python2 support no longer exists in upstream koji. I don't think there's much we could do here aside from retiring koji in epel7, but there's still people using the client.
