Everyday around 1:00 pm I noticed that
sudo apt dist-upgrade -s is running taking a lot of CPU. Enough that it maxes out the rest of the processor and ROS topics start to lag and timing gets off. My PID control loops are now operating on stale feedback topics and it isn’t pretty.
It isn’t clear to me what is causing the updates to kick off each day. I’ve disabled a handful of relevant systemd services. I’ve disabled a handful of cron jobs that seem relevant. I’ve attached a monitor and logged in through the gui and disabled software updates in system settings UI.
My machine is unusable for several minutes. I can typically
kill -9 [pid] of the
sudo apt dist-upgrade process and get it to stop but I’m gearing up for 24/7 autonomous operations and that isn’t really an option.
What am I missing? How do I disable daily updates?
