Since recently upgrading to 20.04 I see informational messages after running apt update similar to

46 upgraded, 5 newly installed, 0 to remove and 0 not upgraded.

31 standard security updates

Googling has failed to turn up the definition of the phrase standard security update. What is it? And, are there non-standard security updates? What possibilities are there?

Seems to a part of ubuntu-advantage-tools to distinguish between freely available security updates (standard) and ESM (paid, later, actual for 16.04 LTS).

May be removed by removing special UA hook by

sudo rm /etc/apt/apt.conf.d/20apt-esm-hook.conf

Above will transform

42 upgraded, 5 newly installed, 0 to remove and 0 not upgraded.

29 standard security updates

to normal traditional behaviour

All this UA ESM stuff on supported Ubuntu versions smells like big BUY word with capital letters.

I found this unacceptable. Especially the viral behavior of UA:

$ sudo apt autopurge ubuntu-advantage-tools

The following packages will be REMOVED:

 distro-info* python3-debconf* ubuntu-advantage-tools* ubuntu-mate-core* ubuntu-mate-desktop* ubuntu-minimal* ubuntu-release-upgrader-core*

 ubuntu-release-upgrader-gtk* update-manager* update-manager-core* update-notifier* update-notifier-common*

After this operation, 6 687 kB disk space will be freed.

Abort.

I have reported a bug 1950692 about ubuntu-advantage-tools "integration".
