As I mentionned, Ubuntu switched off guest sessions by default, and this is an apparmor-level issue. I dont know where Xubuntu / MATE bugs sare reported ?
Thanks for your insight.
Guest sessions still come in very handy.
Sure, but I'm not debating that :)
Now that Ubuntu 16.04 LTS is retired, users are forced to lose their guest-session abilities.
That’s why it has become an uncircumventable problem recently.
I found multiple bugs, dating back 6 years that point out the problems, but they don’t get fixed.
That's why the guest account was disabled by default.
See for further information:
Unfortunately, if even on Ubuntu side there is no traction, it's harder. I dont know what needs to be precisely fixed on AppArmor side, and there are many other Snap-specific issues where I can fix stuff so I can't focus on that.
