Don't do upgrades to Fedora, RHEL, CentOS until you read those.

I'm not sure if it was necessary or not, but I killed all my dnfdragora-updater processes and also commented out the contents of /etc/xdg/autostart/org.mageia.dnfdragora-updater.desktop so that dnfdragora-updater dies if it tries to run

That's for the xfce spin of Fedora 31...

Now all I have to do is remember to re-enable it after the bug is fixed (;-))
