right now gcc-15.2.1-7.fc42, is available on updates-archive but not on updates. this is not a mirror syncing issue since even the dl.fedoraprojects.org master doesn’t have it. is this intended or a bug?
i learned about this because it broke my bootc image build. the fedora silverblue oci image enables updates-archive by default, which meant that when i tried to install gcc-c++, it went for the new version which is incompatible with everything else on my system.
