This question already has an answer here:

I added one conflicting repository by

sudo add-apt-repository ppa:obsproject/obs-studio

and now I would like to remove the repository in my Debian 8.1. I cannot find it in /etc/apt/sources.list.

How can you remove the repository in Debian 8.1?

Use the --remove flag, similar to how the PPA was added:

sudo add-apt-repository --remove ppa:whatever/ppa

or install ppa-purge

sudo apt-get install ppa-purge

then remove

sudo ppa-purge ppa_name

to uninstall any packages

sudo apt-get purge package_name

i think this should answer your question.
