package management – How do i install focal fossa software on groovy gorilla from ppa

I have Ubuntu 20.10. I am trying to install Handbrake from its ppa. when i added handbrake repositories and ran sudo apt update i got the following message

Ign:11 http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu groovy InRelease
Err:12 http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu groovy Release
404 Not Found (IP: 91.189.95.83 80)
Reading package lists… Done
E: The repository ‘http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu groovy 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.

I went to the repository and tried to manually search for groovy packages and found none but there was a focal fossa package.What should i do?

BTW

  • snap packages are outdated
  • I am facing the same issue for other software also.(eg – f.lux…many more)
