Repeated messages to install ubuntu base on fully updated 20.04 desktop system. Why?

  • 772

Just curious - is it normal after doing an apt-get update then upgrade to repeatedly receive messages telling me to install ubuntu base on my desktop computer?

Reading about what ubuntu base is makes me wonder why do I need it on an operating system?

enter image description here

I haven't clicked on "Install now" but usually do an apt-get update followed by upgrade. And just doing only apt-get update, now I see:

  1. The only way for me to get around this was to completely remove Skype. Now I have yet a different problem with skype repositories but since it doesn't specifically apply to this post, I'll just leave it solved.
