This is a bug yet once again in the latest version of 16.04.1, that was installed fresh back in November.
sudo rm /etc/apt/apt.conf.d/20auto-upgrades does NOT work. I have to edit 10periodic and set everything to 0, but once you set security updates to download and install automatically, it once again goes dim on next launch of Software and Updates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1554099 Title: Changing what action for security updates unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1554099/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
