E: The repository ‘http://ppa.launchpad.net/codeblocks-devs/release/ubuntu focal Release’ does not have a Release file.

I’m running Ubuntu 20.04 via WSL on my Windows 11 PC. Today I got this distracting message when I tried to do an apt update

E: The repository 'http://ppa.launchpad.net/codeblocks-devs/release/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Is codeblocks obsolete? Either way. the repo has to go. It took me a while to find the command to remove codeblock repo from my distrubution. Here it is for reference.

sudo apt-add-repository -r ppa:codeblocks-devs/release

Now, I can sudo apt update and sudo apt upgrade to my hearts delight.
