SUMMARY
I have no password, tried to use run0 inside yakuake, it spawned a window just to close it but that was enough for yakuake to lose focus and auto-close

STEPS TO REPRODUCE
1. Have no password
2. Trigger anything requiring polkit authentication (such as run0)

OBSERVED RESULT
Window appears and momentally disappears

EXPECTED RESULT
No window at all

Comment 1 Nate Graham 2024-09-19 21:08:17 UTC 
When you say "I have no password", do you mean you've set your password to be blank? Or that you have somehow removed the password entirely through some means? These are different things, and while the former I believe is expected to work, the latter may result in undefined behavior.
Comment 2 Ilya Fedin 2024-09-19 21:39:00 UTC 
I mean the latter. You can use passwd -d to remove it but not every distro works correctly with that due to pam configs. Perhaps the most simplest way to test it is Fedora since it allows to not to set password in first place on installation.
