I am using this command to try to download qBittorrent

sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable

However, I am getting this error:

E: The repository 'http://ppa.launchpad.net/bitcoin/bitcoin/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.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Why does the "bitcoin" repository cause an error for bittorrent, which is something totally different? Obviously, there is something I don't understand here about packages/repositories, but why does this request for many other applications (ubuntu, mongodb, ethereum, etc.)?

    It's a coincidence. Your failure to remove the dead PPA is unrelated to adding a different PPA. Remove the dead PPA, and the error will vanish. Since qbitorrent is in the Ubuntu repositories, you don't need a PPA anyway. – user535733 Jun 12 '21 at 00:11

  • 3rd party sources (ie. PPAs) are your responsibility to perform checks, ie. are they maintained, trustworthy etc.. A quick check using detail on your paste and I can see the PPA you added doesn't support focal (has been ignored since 2018) and should not have been added.. do you perform required security checks before adding the source? – guiverc Jun 12 '21 at 00:33
  • You don't need to add a PPA to install qbittorrent because it is available in the universe repository. You can install it in the software center or using apt – Nmath Jun 12 '21 at 01:38
