Repository not found

Question

I'm getting E: The repository 'http://ppa.launchpad.net/deadsnakes/ppa/ubuntu hirsute Release' does not have a Release file. While running sudo apt update in a LTS 20.04 server, I'm currently trying to install python3 but it seems it's not being found either. Not sure what to do. Any assistance?

Answer 1

Solved - was apparently using 21.04 but didn't realize when I was meant to use 20.04, don't know how the other stuff started.
