@Julian: When running u-u at shutdown the expectation is that it runs to completion including the downloads (started by u-u-s).
When running in periodic mode triggered by apt's timer it finishes the transaction on TERM signal then it exits to let the shutdown continue. In this case you are right it does not perform the download and installation steps in the same service. In apt-daily-upgrade's case the 900 second is probably future-proof unless the machine/disk is very slow. There are still installer packages which need downloads even during installation, but they are not updated very often. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690980 Title: unattended-upgrades does not block shutdown of system, as it is designed to To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1690980/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
