Earlier, I was getting the following error when execuing
Failed to fetch http://ppa.launchpad.net/deb/dists/http/ppa/ubuntu/main/binary-i386/Packages 404 Not Found
I found the corresponding deb-src inside the file
/ect/apt/sources.d/ containing the lines
deb http://ppa.launchpad.net/deb http/ppa/ubuntu precise main deb-src http://ppa.launchpad.net/deb http/ppa/ubuntu precise main
Upon commenting out those lines,
apt-get update ran without any reported errors.
I'm curious as to why these particular lines were the cause for the reported errors on update, and are the packages linked to that ppa important?
