Comment 10 for bug 1760910

Let me know if this is a different bug and I will file another report, but I think that it's the same.

I open a .deb with gdebi-gtk. The GUI opens. I click "Install" and gdebi simply closes.

If I open a terminal and type gdebi-gtk path/to/deb.deb it opens the deb in the GUI and when I hit install, it actually installs.

The method of adding gksu above doesn't work for me and most others because gksu is deprecated and not installed in Ubuntu anymore by default. It's a good workaround for those who can use it but it still need fixing.

I'm using gdebi 0.9.5.7+nmu2 and Xubuntu 18.04 (upgraded from 17.10 if that makes any difference).
