You missed autoclean. I typically only run autoremove upon reboot. You can also set the update to happen automatically so that all you have to do is run upgrade.
Thank you for "autoclean". I'll check that. > You can also set the update to happen automatically so that all you have to do is run upgrade. I'm in "testing". Sometimes, even with "-y", I'm asked to validate some messages (often inside a vi prompt).

It cleans out unnecessary packages.
All the update does is download the latest available updates so it should not be prompting. My experience is that only upgrade/dist-upgrade will prompt.
I've got a VM running ubuntu 16.04-beta and it seems to be fine.
