Nejde se odhlásit, vypnout ani restartovat z aktivovaného temporary guest session. Pouze via tty or REISUB. Po kliknutí na cokoliv v dialogovém okně pro odhlášení/restart/vypnutí dojde jen k hlášení "Při odhlašování došlo k chybě" GDBus.Error:org.freedesktop.Dbus.Error.InvalidArgs: Type ofmessage, "(yb)", does not match expected type "(b)"

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1921920/+editstatus and add the package name in the text box next to the word Package.

Sorry - in this case, I was unable to identify a specific package, but I listed the error message and the situation when it happened.

There is a bug in Xubuntu 20.04.2, probably on the lightdm side, which manifests itself in such a way that if a Temporary Guest Session is activated and the user logs in to that session, he cannot log out. It is therefore necessary to reboot via console after admin login using "systemctl reboot -i". Or REISUB. However, sometimes a fictitious Guest user is created, but it is protected by some fictitious password, and what is worse it is not listed anywhere in the GUI user list.

I deleted the related entries in /etc/passwd and /etc/passwd- , deleted /tmp/ and rebooted. The dummy accounts no longer haunt me in lightdm. However, this does not solve a very annoying bug for me ...
