Apologies if this is obvious or off point, but found this problem thread on encountering the same issue. This occurred for me when there was a user level override of dnfdragora settings in place. The work around was deleting ~/.config/dnfdragora.yaml to stop the hang. To avoid rebooting/relog, I had to kill both dnfdragora-updater and sudo kill dnfdaemon-system then re-launch dnfdragora-updater.

From a terminal: $ rm ~/.config/dnfdragora.yaml $ killall dnfdragora-updater $ sudo killall dnfdaemon-system $ dnfdragora-updater &
