​​Hi, Not only is CentOS 7.9.2009 not available (see my previous e-mail request to get it added), but most of the other repos I am interested in, does not work either. In my home project 'home:DOlsson', I have defined a few repositories mapping to the repositories "Fedora:EPEL:7/RHEL" + the respective CentOS repo, i.e. "CentOS:CentOS-7/7.{7.1908,5.1804,4.1708}". When trying to build using the repositories "CentOS:CentOS-7/7.5.1804" and "CentOS:CentOS-7/7.7.1908", both breaks off with an error message: bash-4.4$ osc build --clean 'Fedora_EPEL_7+RHEL75+CentOS75_1804' x86_64 ... CentOS:CentOS-7/libnetfilter_conntrack: attempting download from api, since not found preparing download ...Server returned an error: HTTP Error 301: remote error http //vault.centos.org/centos/7.7.1908/os/x86_64/Packages/intltool-0.50.2-7.el7.noarch.rpm remote error Moved Permanently bash-4.4$ bash-4.4$ osc build --clean 'Fedora_EPEL_7+RHEL77+CentOS77_1908' x86_64 ...

Oddly enough, though, when using the 7.4 repo, it works: bash-4.4$ osc build --clean 'Fedora_EPEL_7+RHEL74+CentOS74_1708' x86_64 ...
