Hey there the "Software" app in GNOME fails to refresh the cache although it has the URL set to http://mirror.centos.org/$contentdir/$stream/AppStream/x86_64/os/repodata/repomd.xml which presumably resolves to this: http://mirror.centos.org/centos-8/8.0.1905/AppStream/x86_64/os/repodata/ It would seem that it just reads the baseurl from /etc/yum.repos.d/Centos-Stream-Appstream.repo and yum repolist returns fine so I'm wondering how to troubleshoot this ? Currently the "Software" app shows no software at all which is a shame. Please do let me know if this is a known issue thanks very much.
