I'm under ubuntu 20.04 LTS and I got the below error while I apt-get update my system:

E: The repository 'http://ppa.launchpad.net/danmbox/ppa/ubuntu focal Release' does not have a Release file.

I tried to search for a solution to remedy this error but I didn't find a reliable path, and I don't need to occur other system problems using wrong or inadequate solutions. help me, please!
