according doc After installing Ubuntu 16.04, apt update and apt upgrade will run on boot and every day at 6:00 and 18:00 automatically. And only security upgrade will be applied. Now in 'Software & Updates' I have 'Download and install...' for security updates but I see some security updates waiting for my confirm. see screenshot. I attached also some log. I opened also another bug for the same problem: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1666225
