Comment 13 for bug 1904098

Hello!

Thanks for maintaining snapd packages!

I recently got an upgrade of snapd on Ubuntu 20.10 Hirsute. I only use it for Chromium, mainly to attend some meetings. Chromium had been updated 12 days ago according to 'snap info'. It has been restarted since then. "lxd" has not been upgraded recently.

After the upgrade, my microphone was not accepted in a meeting. I restarted chromium but nothing happened: it didn't restart. I quickly checked with "ps" and there was one process started and related to chromium: /snap/bin/chromium. Relaunching Chromium added one process like that.

I also did: "snap list" but nothing was printed and it looked stuck, I didn't get the prompt back.

Sadly, I didn't have time to investigate more because I was expected in a meeting so I did a Windows (reboot) and after it was OK. I didn't try to restart snapd services :-/

After the reboot (and the meeting), I tried to collect more logs:

 $ journalctl -u snapd -b-1

Not sure it would help. I didn't find any logs related to snapd in /var/log.
