Hi Doug,
I'm really curious to find out what got you into that situation. Trying to add the X2Go stable PPA on a stock Ubuntu 20.04 (with X2Go from the Ubuntu Repo already installed) and trying to install/upgrade did throw error messages, but did not leave my system in a broken state.
Things that might be helpful in debugging the issue: The output of
grep -r x2go /etc/apt/sources.list*
(as this will show all x2go-related repositories you are using)
as well as
cat /var/log/apt/history.log
and, if your log rotation has already moved 2023-05-31's entries into the gzipped archive logs,
zcat $(ls -1 -r /var/log/apt/history.log.?.gz)
The "Commandline" entries should show exactly which apt commands you ran that got you into this mess.
Kind Regards, Stefan Baur
