[X2Go-User] x2go upgrade issues (packages with unmet dependencies)

[Stefan Baur]

Hi Enrico,

I just tried to reproduce your issue.

What Mihai (ionic) pointed out to me is that you had a mix of X2Go 
packages from Ubuntu itself and from the X2Go stable PPA.

So I tried adding the stable PPA to an Ubuntu 20.04 machine that has 
been running X2Go stock from the Ubuntu repositories.

I was able to add the PPA, I was able to run apt update, but when I tried

apt install -d x2goserver x2goserver-xsession

it started throwing errors already. But it did not break the existing 
installation.

Trying

apt full-upgrade -d

I got a clear warning that several packages with x2go in their name 
would be uninstalled if I decided to continue.

Sooo ... I'm really wondering how you could get your system into that 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
