Oh, interesting. The application is actually still running when it is updated in the background.

So in recent versions the behavior changed. After I update Signal the application is still running, but if I then click anywhere on the application it will quit by itself. I then have to start Signal again. Better behavior I guess, but a full restart by the application itself would be better I think (or just the possibility to be updated while running and not having to restart).

I noticed this issue was still open. The current behavior (since several years) is that an opened Signal doesn't crash after it is updated in the background. You can continue using it (i.e., the old version). Once you click on Preferences or About Signal Desktop (and possibly other menu items) it crashes though.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

After an update, Signal still crashes on Linux, for example when restoring from tray.

@tribut This is terrible. Sorry you ran into it. Could you give us a debug log, please?
