I booted my xenial system in a VM, and tried to verify it; but: The hierarchy of apt-daily-upgrade.service is:
apt.system.daily install - apt.systemd.daily lock_is_held install - unattended-upgrades only the top-level process is terminated. Manually sending SIGTERM to unattended-upgrades makes it exit; but it seems the SIGTERM is not forwarded through the shells. The result is simple: The big lock protecting against update and co is released (not that problematic), but upgrades are never stopped. I'm not sure if systemd still waits for the runaway processes on shutdown; if that's the case, then it sort of works. We'd have to verify that somehow. So, if we want to have a time out working, we have to get rid of the shell script it seems. Which sucks a lot. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1690980 Title: unattended-upgrades does not block shutdown of system, as it is designed to Status in OEM Priority Project: Triaged Status in OEM Priority Project xenial series: Triaged Status in apt package in Ubuntu: Fix Released Status in unattended-upgrades package in Ubuntu: Fix Released Status in apt source package in Xenial: Fix Committed Status in unattended-upgrades source package in Xenial: New Status in apt source package in Zesty: Fix Committed Status in unattended-upgrades source package in Zesty: New Bug description: Title: No pop-up window to warn users that system should not reboot or shutdown while installing security updates Summary: No pop-up window to warn users that system should not reboot or shutdown while installing security updates Steps: 1. trigger unattended-upgrades 2. reboot or shutdown system while installing packages Expected results: There is a pop-up window to warn users that system should not reboot or shutdown Actual results: There is no pop-up window to warn users Additional information: $ apt-cache policy unattended-upgrades unattended-upgrades: Installed: 0.90 Candidate: 0.90ubuntu0.5 $ lsb_release -rd Description: Ubuntu 16.04 LTS * APT SRU * [Impact] Stopping apt-daily-upgrade.service terminates dpkg and friends by sending the signals to all processes in the cgroup, and will send KILL quickly after. [Test case] Start apt-daily-upgrade.service and stop it while unattended-upgrades is running. The upgrade should run to completion or a safe exit point as long as it takes less than about 900s (which is the timeout for sending kill). [Regression potential] Leftover processes might remain in the apt-daily-upgrade cgroup if the postinst scripts or some apt hooks do something funny. Shutdown might take longer due to the 900 second timeout.
