Not what I wanted to hear, but what I needed to hear. I'm glad to get clarity. Thanks for that. Does that mean I have to do a complete reinstall and lose all my installed apps? I assume so because the "upgrade" option does not appear to work generally speaking.
For the upgrade it will not remove your programs.
I also say the upgrades are pretty smooth in my opinion.
To Upgrade: Alt + F2 then launch update-manager -cd
I do recommend always backing up important files for any upgrade
I don't see an Update Manager option, but I see a kernel update option "How To Update / Install Linux Kernel". Could it be that?
Next closest option is "Ubuntu MATE Guide"
After Alt+F2, type update-manager -cd

Got it. Well, this is an example of what I was talking about. I obviously have an internet connection, because we're chatting right now. But after running the command you recommend, the Software Updater displays the following error message:
Failed to download repository information
Check your internet connection.
Well pluviosilla,
I do not want to give you bad or wrong information.
I will be honest and tell you that I am not sure what the answer is for that. Sorry I cannot help more.
No problem. You've been a huge help already. Much appreciated.

The software updater is trying to download drivers from this URL, but the drivers are no longer there:
This thread makes clear that it is impossible to upgrade from 17.10. So I guess there is no way to my installed apps. Therefore my final question is: how do I reinstall Ubuntu without at least destroying my data?
That is an old version and we need to do a few things to get you on the path to a supported version. You will need to update your /etc/apt/sources.list
The correct address is old-releases.ubuntu.com

For example if you have this in /etc/apt/sources.list
deb http://us.archive.ubuntu.com/ubuntu/ zesty multiverse
We need to make that read:
deb http://old.releases.ubuntu.com/ubuntu/ zesty multiverse
You will need to do this for all of your sources.

Is the problem that I'm sourcing "artful"?
BTW, following the post I linked to above, I tried replacing "artful" with "bionic". But I still got errors.
Can you disable this ppa and try again, uncheck in the GUI or comment it out #
I made an attempt to follow your suggestion. Here's what I did:
From top menu: System => Administration => Software & Updates
In the list found on the "Other Software" tab, I unchecked the PPA boxes.
Ubuntu then attempts to update the "cache" and tries to download something from old-releases, eventually throwing the following error:
Failed to download repository information
I removed all the files in /etc/apt/sources.list.d and reran:
"sudo apt-get update"

Please check the following page for instructions on what to do to solve your problem. Good luck pluviosilla.
The syntax looks wrong on 2 of your sources.
Try changing http://old-releases.ubuntu.com/ubuntu artful.updates InRelease to:
http://old-releases.ubuntu.com/ubuntu artful-updates InRelease
and
http://old-releases.ubuntu.com/ubuntu artful.updates Release to:
http://old-releases.ubuntu.com/ubuntu artful-updates Release
