Hi there,

The manual way of doing this is, to use the grep command and search for any references of the webupd8team repository in your source list:

  • sudo grep -r "webupd8team" /etc/apt/*

After that using your favorite text editor open the file and remove the line referencing the `webupd8teamz repository.

Finally, run:

sudo apt update

Another option is to use the apt-add-repository command with the --remove flag:

sudo apt-add-repository --remove repo_name_here

Hope that this helps!
Regards,
Bobby
