After a discussion with Michael Vogt I tested this with unattended- upgrades version 0.92ubuntu1.4 from yakkety-updates and observed the shutdown blocked temporarily (message in plymouth about updates being installed) when I shutdown the system with unattended-upgrades running.
I was connected via ssh when running the unattended-upgrades and saw the following: Preparing to unpack .../18-libreoffice-style-galaxy_1%3a5.2.2-0ubuntu2.1_all.deb ... Unpacking libreoffice-style-galaxy (1:5.2.2-0ubuntu2.1) over (1:5.2.2-0ubuntu2) ... Connection to clean-yakkety-amd64 closed by remote host. Connection to clean-yakkety-amd64 closed. In plymouth I also saw the message about "libreoffice-style-galaxy". Could you please retest and ensure you shutdown the system when packages are being unpacked / installed? -- 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: No pop-up window to warn users that system should not reboot or shutdown while installing security updates Status in OEM Priority Project: Confirmed Status in OEM Priority Project xenial series: New Status in unattended-upgrades package in Ubuntu: Incomplete 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 To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1690980/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
