Every time when I run the sudo apt-get update command I get these errors:

W: The repository 'http://ppa.launchpad.net/tualatrix/next/ubuntu zesty Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/tualatrix/next/ubuntu/dists/zesty/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

Can anyone please help me in that?

    That usually means there are no packages for this Ubuntu release. Indeed, the PPA was last updated 141 week ago, and the latest packages are for 14.10. Run sudo ppa-purge ppa:tualatrix/next to remove it. – mikewhatever Oct 20 '17 at 18:37
  • Tried the said command, but it still gives me the same errors that I mentioned. – rahul singhal Oct 20 '17 at 19:17
  • You must update the package catalog. Run sudo apt-get update after removing the repository.. – Jaime Oct 20 '17 at 19:32
  • Restarted the system after running the ppa-purge cmd, it still gives me the mentioned errors when I run apt-get update . – rahul singhal Oct 20 '17 at 19:38
