Auto Update not a Full Update

[dan-mcmanus5]

I have not received any more update notifications since posting here and following your recommendations

To be clear, the recommendations given were basic maintenance, and are unlikely to have affected the notifications. It was a separate issue.

Here’s a little background on (likely) why you received the notifications, and what to do about it…

Unattended Upgrades is included on every release of Ubuntu (except Ubuntu Core, which doesn’t use apt). UU is made up of two jobs, and those jobs run semi-randomly twice daily.

• One job does the equivalent of apt update.
• A different job does the equivalent of apt upgrade

Since these run semi-randomly, many hours might separate the two. And during that time, you might get a (true) notification that “upgrades are available.”

What to do about it? Nothing. On a properly working system, the second job will handle it automatically.

So why do you get a notification at all? Well, for two reasons:

1. Not all updates are security updates. ONLY security updates are automatic on a stock install of Ubuntu. Other updates (bugfixes) are not. You changed that, but there still might be other updates --like from non-Ubuntu sources-- that still won’t be automatic.

2. It’s the way you will learn if Unattended Upgrades isn’t working for some reason.

Since you are not getting any more notifications, it seems likely that Unattended Upgrades is working properly, and you are indeed receiving completely automatic upgrades of Ubuntu packages (but not non-Ubuntu packages).

Along with @ian-weisser great advice and suggestions I would still get rid of the Debian Media repo.
