Adding and Removing PPAs in ubuntu

if you're trying to remove a ppa after using add-ppa-repository, it looks like you don't need the ppa-purge deb package.

i just installed a ppa from wikigames, and when sudo apt-get update didn't work after sudo add-apt-repository ppa:wikigames/ppa, i downloaded the ppa-purge .deb from here and it didn't work to remove the ppa. Found out all i had to do was

cd /etc/apt/sources.list.d and sudo rm wikigames.list.
