Welcome to the Forum!

Open Software & Updates and on the first Tab choose ''Main Server'' as Source. then try it again.

Thanks, @StarTreker . As they say: "A picture is worth a thousand words.", and that is so true. I've been advised many times to always use the main server, but had no idea where to find, or how to change it. I remember also being told to "launch Nautilus", so I searched my laptop, I searched in Google too but I couldn't find out what Nautilus was, let alone how to launch it! In the end, @Ponce-De-Leon saved me by posting screenshots.

I'm eternally grateful to all the thoughtful and patient contributors in this community. Many, long-term, Linux users forget that us noobies just don't have the vocabulary sometimes, and give perfectly accurate instructions, which leave us nonplussed, confused and feeling stupid. It can be a steep learning curve.

We all started at one Point. So, that is no Problem. And to be fair: When Gnome would name their Programs with the actual Program Names, it would avoid Confusion.
