PSA: unattended-upgrades restarted nginx in the middle of my stream (lemmy.world)

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?

I've been burnt by this, my nginx lxc on proxmox was crashing at about 6:30 every morning for a week. Turns out auto update and debsecure was running on it and using all the 512mb of memory and the lxc would get killed by the host, so removed both as I update Tuesday evenings anyway

    512mb and getting killed every morning at the same time sounds like a fun one to track down lol. a fixed weekly slot like your tuesday evening is probably the sanest setup honestly, I just know I'd forget.

    I have some of my works colleagues join and we all do system updates and talk crap for the evening, its a great way to help others sort things

    that's actually a nice idea, updating with people around makes it way less of a chore, and someone always knows the weird fix. I'd probably steal it if I had more than one box to look after.
