This hang stalls the shutdown process for 5-10 mins. If I disable unnattended-upgrades via the /etc/apt/apt.conf.d/20auto- upgrades and/or 50unattended-upgrades, the problems occurs. If I terminate the service before shutdown/reboot (sudo service unattended-upgrades stop) the problem still occurs. If I remove the package (sudo apt remove unattended-upgrades) the problem no longer occurs. This occurs on a freshly installed version of Ubuntu Server 16.04.1 (both unattended-upgrades installed via install GUI or manual install of unattended-upgrades) Both Kern.log & syslog do not show the shutdown process (I believe because the filesystems have already unmounted) Original report: http://askubuntu.com/questions/878630/apt-unattended- upgrades-stalls-shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1661611/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
