Package: x2godesktopsharing Version: 3.2.0.0-0~283~ubuntu18.04.1 So I installed X2Go with x2godesktopsharing inside some docker container. If I would share a remote desktop session, it could not be found by the client. I found out that x2golistdesktop calls "ss". This was not installed. There was no error and it failed silently. The ubuntu package iproute2 contains the ss command. I suggest you add this to the dependencies.
