[Bug 1854588] Re: gdebi-gtk calls pkexec inappropriately

[Alkis Georgopoulos]

The problem is not in firefox or mate, it's in gdebi-gtk, and
specifically in GDebiGtk.py, line 619:

os.execv(pkexec_cmd, pkexec_args+gdebi_args)

This replaces the current process with a pkexec call. This is not a
valid usage of pkexec, as pkexec requires the parent process to not be
init (ppid!=1).

To reproduce the issue without firefox, one can just run `setsid gdebi-
gtk package.deb`.

In a similar bug report for update-manager (LP: #1020115), this flag was
used instead of os.execv:

flags = GObject.SPAWN_DO_NOT_REAP_CHILD

Is gdebi still maintained by Ubuntu developers, or should we report this in Debian?
Can we propose a patch similar to the update manager, or even just use a simple shell wrapper?

** Summary changed:

- Clicking 'Install' on gdebi-gtk makes it vanish ONLY when .deb opened from Chrome/Firefox
+ gdebi-gtk calls pkexec inappropriately

** No longer affects: firefox (Ubuntu)

** Project changed: ubuntu-mate => gdebi
