This question already has an answer here:

So I'm running the following command:

$ sudo apt-get update

When I do, I get the following errors:

Err http://ppa.launchpad.net precise/main Sources
  404 Not Found
Err http://ppa.launchpad.net precise/main i386 Packages
  404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

In Software Sources, I attempted updates from the United States server as well as the main server but the error persists.

I also don't know what these sources provide. I am having difficulty compiling certain packages from source code. Do these sources update any packages that affect this process?

"amith kk" is a PPA which at present time appears to only provide "unity-reset" tool. A tool used to reset Unity & Compiz, apparently

I assume you added this PPA to the Ubuntu repositories, and perhaps...that PPA is not accessible while doing the standard apt-get update?

Also, error message at top http://ppa.launchpad.net precise/main Sources By navigating through the URL, I can only get up to http://ppa.launchpad.net...."precise" was nowhere to be found in the sub-directories. It could be a bad URL, hence the 404 error?

That would make sense. I was repairing my Compiz package last week because it was bugging out when opening YouTube videos in full screen. I suppose the best fix is to remove the sources then. Thanks! –  baph0mt Sep 21 '13 at 4:00
