[X2Go-User] x2go to access Linux - issues with graphical updates

X2Go Client v. 4.1.1.1 (Qt - 5.9.5) Guest Linux Mint  5.4.0-66-generic #74-Ubuntu SMP x86_64 Host   Linux Mint  5.4.0-67-generic #75~18.04.1-Ubuntu SMP x86_64

Guest is where the issue is occurring.. host is where I'm working from ( x2go client is running)

On Guest,  I open the Linux Mint  update manager.  If I need to do nothing more than approve update, everything works as expected.    However, if I want to change software sources or perform a version up it fails.   Both items require a secondary window to be open, which doesn't happen, at least in x2goclient.

Computer in question has no monitor and is only accessed through x2go (my display port adaptor died).

Thoughts or suggestions ?
