When you see the messages appearing on the screenshot u-u is downloading/installing packages in the background and unattended- upgrade-shutdown is waiting for u-u to finish.
Do you see related activity in /var/log/unattended-upgrades/* ? I assume you have not changed u-u configuration. There should be no difference in using DHCP/static network configuration, but the upgrade process starts only on AC power and is triggered by /lib/systemd/system/apt-daily-upgrade.timer which may also influence testing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1714429 Title: hang on shutdown with static network configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1714429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
