The problem is however this one: http://download.opensuse.org/update/leap/15.3/sle/sle-sp2/x86_64/ These newly released -release packages will cause problems if people migrate from 15.2 now. sle-module-containers-release-15.2-50.1.x86_64.rpm sled-release-15.2-44.7.1.x86_64.rpm sles-release-15.2-52.8.2.x86_64.rpm SLE_HPC-release-15.2-44.6.1.x86_64.rpm SLE_RT-release-15.2-44.7.1.x86_64.rpm We need to remove them (e.g. add them to the rsync blacklist file)
