I was following an old tutorial and did an apt-get installed a repository (I think that's what it was) I am no ubuntu guru. Turns out that repo no longer exists, and when I now do an apt-get update I get this:
W: Failed to fetch http://ppa.launchpad.net/colingille/freshlight/ubuntu/dists/wily/main/binary-i386/Packages 404 Not Found
I tried the usual
sudo rm /var/lib/apt/lists/* -vf
but no luck. Where is the list that stores all the repos that i added myself? How do I get rid of this?
