Here's the error I'm getting:

You might want to run 'apt --fix-broken install' to correct these.

I downloaded code::blocks yesterday, which came with a series of deb files I assumed to be dependencies. I started installing each, but realized that I wasn't going to get it installed with the download I had. Next I added a repository for code::blocks, never got code::blocks installed.
Now when I run sudo apt-get update, I get this error:

And anything I try to install, I get an error:

Any help would be greatly appreciated as I don't want to have to reinstall... I've got everything right where I like it!
sudo apt --fix-broken install? You probably also need to remove the launchpad ppa for codeblocks. You can do this in "Software & Updates" application. – popey Mar 04 '21 at 18:37
