Small thing but it got me last week. I relay my stream to twitch through nginx-rtmp on a cheap VPS, and one morning unattended-upgrades pulled a new systemd, needrestart restarted nginx (and postgres, and everything else) and the stream dropped. OBS reconnected fast but twitch counted it as two streams.
default timer is 06:00 UTC + up to 1h random, which is exactly when I stream lol. moved it with a drop-in:
# systemctl edit apt-daily-upgrade.timer
[Timer]
OnCalendar=
OnCalendar=*-*-* 13:45:00 UTC
RandomizedDelaySec=15m
the empty OnCalendar= matters, without it you just add a second time and keep the old one.
anyone else got bitten by this?
Unattended upgrade?
Why? Specially on critical systems?
If you do such upgrades, schedule for a time you don’t use the system at very least …
There’s few apps I can think of that fail when the service restarts. At worst Jellyfin and Home Asssistant take a minute or so to be available again. The former usually does not pose a problem because of client side caching while streaming. HA would be quite annoying, altough lights etc would keep their current state so it’s unlikely I’d even notice.
That said I don’t use unattended upgrades.
