** Description changed: 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. + + * unattended-upgrades SRU + + [Impact] + + * Undattended-upgrades does not stop quickly gracefully when shutdown/reboot is initiated by the user. + * The fix is performing the updates in minimal package sets and allow gracefully stopping between those steps when unattended-upgrades.service sends a TERM signal to running u-u. The signal is sent on receiving PrepareForShutdown() from logind (https://www.freedesktop.org/wiki/Software/systemd/inhibit/) to stop unattended-upgrades a bit earlier than the shutdown process starts (LP: #1803137). + + [Test Case] + + * Configure the system to have several 20+ packages upgradable by + unattended-upgrades. One easy way of setting this up is starting with a + system where packages from -security are installed but packages from + -updates are not and enabling -updates in u-u: + + # echo 'Unattended-Upgrade::Allowed-Origins:: + "${distro_id}:${distro_codename}-updates";' > /etc/apt/apt.conf.d + /51unattended-upgrades-updates-too + + * Pre-download upgrades + # unattended-upgraded --download-only + + * Trigger unattended-upgrades run: + # service apt-daily-upgrade start + + * Shutdown the system from a graphical user session or by executing + # dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.Reboot" boolean:false + + * Observe the system unattended-upgrades being gracefully stopped, + checking /var/log/unattended-upgrades/unattended-upgrades.log. There + should be packages left to be upgraded. + + [Regression Potential] + + On Xenial (with Unity) starting shutdown from the graphical session does + not log the user out nor show any progress on the shutdown until the + inhibition timer expires which is confusing. Users should be logged out + on PrepareForShutdown() (LP: #1803581).
