I'm not sure I understand. Does it freeze or crash? Or it just stops progressing and doesn't allow to close.
Comment 2 Nate Graham 2018-06-25 15:44:56 UTC 
FWIW,the error "dependency resolution failed pulseaudio=11.1-1 <- pulseaudio-gconf: could not satisfy dependencies." is a package issue with your distro.

Discover shouldn't prevent you from closing it, though. We might also want to provide a more informative error message in a pop-up rather than a passiveMessage, and include some context ("Your distro encountered the following error..." and next steps for resolving the issue or at least reporting it upstream.
Comment 3 Aleix Pol 2018-10-15 13:26:25 UTC 
We need more information to be able to fix this issue.
It doesn't look related to the dependency issue in PackageKit that should never end in a crash.
