Unable to launch some snap packages

  • 772

I'm unable to launch some snap packages after my system crashed a couple hours ago. Everything was perfectly fine before my system crashed. Started happening when I managed to get my system working again.

Discord for example gives me this error:

ERROR: not connected to the gnome-3-28-1804 content interface.

The docker daemon also won't start:

$ snap logs docker

Brave browser also didn't start, at first I thought I just need to re-install, which worked, BUT without saving my brave data, so the browser now doesn't know any of my pages, bookmarks, settings or anything. (I did NOT use --purge when removing). See: Snapcraft removed all my data without --purge for that issue

EDIT: The issue with brave data have been resolved, it did save that data, just didn't auto-restore the data when I reinstalled. (See the link above for details).

Some information:

    In the end this was resolved by following the process of removing and re-installing the snap as mentioned above.

    This did however result in me thinking that the snap data was deleted and not backed up correctly. Turns out that it is backed up but you have to manually restore the backed-up data. See this question for more details on that
