The qt5 libraries in RHEL 8.5 are at a higher version than they were in RHEL 8.4. This is causing RHEL 8 machines that have the KDE Plasma Desktop unable to do an update due to qt5 version dependencies.
A rebuild of the KDE Plasma Desktop in EPEL8 is currently underway. It usually takes 3-4 days for all the packages to be rebuilt, as long as the builders co-operate. We expect the packages to be in epel8-testing by Monday, November 15.
Thank you for your patience. Troy Dawson
