The update failed for mint 20.3 as x2goserver-x2gokdrive requires xserver-x2gokdrive which is not available in mint 20.3 and not available from the x2go repository.

It screwed up my system pretty good! had to do a clean install of 4.1.0.3 to get up and running again.

I have been using x2go for years, love it!

And also some documentation file was moved in 4.1.0.3 to a different file in 4.1.0.4 and the

upgrade complains about that before even reporting the kdrive issue on an attempt to do a fresh install of 4.1.0.4.
