How to stop Ubuntu pro nagging?

[Carsten Agger]

Hi all

Some time ago, I installed Ubuntu 22.04 on my girl friend's computer.

I tried to set it up to only do automatic updates, but it turns out it's 
constantly coming up with exhortations to "Install Ubuntu Pro" and 
telling about updates that require Ubuntu Pro.

How do I remove all traces again, so that it will never recommend her to 
upgrade to Ubuntu Pro ever again?

Note, I don't want to discuss the pros and cons of Ubuntu Pro, it's just 
that these prompts are annoying and she wants them to go away. :-)

Best, and thanks in advance for any response :-)
