Please describe more clearly how you determined the stuff you put in parenthesis. Given the last one, I'd try just reinstalling it.

Thanks for responding.
the words in parentheses are the error messages that pop up.
As described, I tried reinstalling and it didn't work. The system thinks it's both installed and not installed, but won't uninstall it or reinstall it.
Firefox is working fine, but some websites don't like it, so I used Chromium as a backup.

Can you please be more precise on each step? For example:

--->
Before: attempting to run Chromium fails (not installed- though Software shows it is)

After: In the terminal:

  $ chromium
  chromium: command not found
<---

[Nathan Teodosio (nteodosio)]

Are you using the graphical user interface programs (such as the snap store) in all your attempts or do you use the command line?

If the former, please try

  sudo snap remove chromium
  sudo apt remove chromium-browser

and report back with the error messages you get then.
