[George Kitsopoulos]

When I try to install some deb packages gdebi disapears. It does not show me any error report. It will just disapear from my screen.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm a Xubuntu flavour user and I've never seen Gdebi work (17.10-19.04). It just closes immediately after I press "Install" button. If I run Gdebi with root privilege through terminal (sudo -i gdebi) then it works.

Hello
what is the status of this bug,
I just have installed an ubuntu version (elementaryOS) and I have this bug

This bug still exists in Ubuntu 22.10.

If you open it via the command line (even without sudo/root) it will work and prompt for the password. And if you open it via menu (my .desktop file has `gdebi-gtk %f` as the command) and THEN load the .deb, it will also work.

I also tested it on different file managers:

Elementary Files (does not work)
Nautilus (does not work)
Thunar (does not work)

Caja (works)
Nemo (works)
PCMan (works)
Rox (works)
Thunar in root mode (works)

So, seems to be something to do with the way it launches or the way the file is passed to it when it launches maybe? The fact that it doesn't work in Thunar normally but works when Thunar is launched in root mode is strange, don't know if that info helps.
