This question already has an answer here:
I`m trying to update & upgrade my current version of Ubuntu but I have some problems : When I run apt-get update i get the following errors :
W: Failed to fetch http://ppa.launchpad.net/antonio.chiurazzi/ppa/ubuntu/dists/quantal/main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/antonio.chiurazzi/ppa/ubuntu/dists/quantal/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
I removed the sources from
var/lib/apt/lists but I still receive the same error. Can anybody tell me what's happening and how i can remove that to successfully update my Ubuntu ?
My configuration : Ubuntu 12.10 on Intel I3 processor with 4gb DDR3 RAM.
