[nmglug] Where is apt config?

Hi NMGLUG folks, Especially to Jason: Thanks again for all of your help. I have a question about what you wrote in your latest email. You wrote: You need to take the kdenlive ppa out of your apt config. Adding Ubuntu repositories to your Debian is a good way to break your system. ... Remove the ppa first and try again. I looked around, especially in the etc folder. I looked for places indicated on https://www.debian.org/doc/manuals/aptitude/ch02s05s05.en.html I have not yet found where my apt config is located. Please help. LeRoy -- I am the Love of God, no matter what. LeRoy Diener 213-LEROYIZ 213-537-6949 www.leroydiener.com/
