I added the PPA using this command:
sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable
I entered the password and hit enter.
In the 13th process, I encountered this error:
http://ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/ubuntu focal Release
404 Not Found [IP: 91.189.95.85 80]
I also encountered:
Err:14 http://ppa.launchpad.net/morphis/anbox-support/ubuntu focal Release
404 Not Found [IP: 91.189.95.85 80]
I think this has to do with the version of Ubuntu that I am using, (ubuntu focal 20.04), in the end, there was this message:
E: The repository 'http://ppa.launchpad.net/kirillshkrogalev/ffmpeg-next/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.

What should I do?
I can't post the full process as it has too many links.
