Fun story: unattended-upgrades upgraded docker-engine in the middle of a day, breaking gitlab CI builds until a sysadmin figured out what happened and rebooted the machine manually.
unattended-upgrades has an option to postpone unattended reboots to some safer time (like 2AM). Perhaps a similar option to postpone unattended- upgrades themselves would help with this? It's probably fine to run other apt-daily activities (like running apt update or apt upgrade --download-only) during the day. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1615482 Title: apt-daily timer runs at random hours of the day Status in apt package in Ubuntu: Triaged Bug description: apt, from 1.2.10 onwards (ie any version in Xenial, onwards) uses a systemd timer instead of a cron.daily job. This is a good thing, decoupling apt daily runs from the rest of cron, and ensuring other cron.daily jobs are not blocked by up to half an hour by the default settings of unattended-upgrades. However the policy chosen is to have the apt daily script run at a random hour of the day in a wrong headed attempt to reduce server load. This has the side effect of running unattended-upgrades at random hours of the day — such as business hours — rather than being confined to between 6:25am and 6:55am, using the defaults. A better policy would be to have the script activate at 6:00am plus an interval of 20 minutes at one second intervals reducing the impact of timezone population spikes, while still allowing unattended-upgrades to run within a predictable interval, before 7am. At the very least, some sort of note in the NEWS file detailing the new behaviour would be welcome.
