When upgrading from F30 to F31 I get Problém 18: package system-config-users-1.3.8-6.fc29.noarch requires python2-libselinux, but none of the providers can be installed - python2-libselinux-2.9-1.fc30.x86_64 does not belong to a distupgrade repository - problem with installed package system-config-users-1.3.8-6.fc29.noarch Package system-config-users has been retired and should be obsoleted.
