http://packages.x2go.org/epel/ doesn't have a subdirectory for CentOS 8.
Is there a better X2go repo for CentOS 8?
I'm running pyhoca-cli-0.6.1.3 on the client and the server is running x2goserver-4.1.0. I understand that there is a known incompatibility between the two versions which has been fixed upstream.
