Having fixed the missing python3-invoke module pyhoca-cli now crashes
in all sorts of other ways on my xubuntu 20.10 system.
These sessions run fine when called from x2goclient, I just want to script them
in order to run a couple of things before the x2go session.
This is calling an xfce session, i.e. a full desktop:-
