"Expanded Security Maintenance for Applications" shown every time I log on!

[Bo Berglund]

My Ubuntu 20.04.5 LTS has started to display a message as the subject shows when
I log on via SSH.
SSH (PuTTY) is the *only* user access to this server, it does not have any
monitor or keyboard attached.

And the new message is delaying the connection to the system too!
I think it started a month or so ago.

Before it started I could log on almost instantly but now after entering
user/password there is a considerable delay until the start message is shown.

And now it looks like this:
--------------------------------------------------------------------

--------------------------------------------------------------------

The system is fully updated (apt full-upgrade) and rebooted today.

When I google the message it seems to be some "subscription" I have to do etc.

Notice that this system is a *server* installation and there is NO GUI at all!

How can I get rid of this message and speed up the logon?

I do *not* need any extra functionality and there are no humans logged on except
occationally when I am doing maintenance via SSH.
