Hello list, I'm trying to perform a local build of a package for CentOS_7. I can successfully execute "osc build openSUSE_Leap_15.3" for the package. It runs inside a qemu-kvm virtual machine and works as expected. However, I cannot run "osc build CentOS_7" for the same package. This is what I'm observing: The beginning of the log looks normal: Building nccmp.spec for CentOS_7/x86_64 Getting buildconfig from server and store to /home/***/nccmp/.osc/_buildconfig-CentOS_7-x86_64 Getting buildinfo from server and store to /home/***/nccmp/.osc/_buildinfo-CentOS_7-x86_64.xml Updating cache of required packages 0.0% cache miss. 253/253 dependencies cached.
