Update Manager : Failed to download repository information

[jamesallen4u]

Hello everyone,

For the past week, whenever I try to update via the Update Manager, I get the following errors:


[W:Failed to fetch http://ppa.launchpad.net/pmcenery/ppa/ubuntu/dists/precise/main/source/Sources 404 Not Found
, W:Failed to fetch http://ppa.launchpad.net/pmcenery/ppa/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.

Here is the screenshot:

My internet connection works perfectly as I am able to access this forum. I don't understand the sources of these errors since I am still learning to use Ubuntu. Please help me out with this error. Thanks in advance for your help.

Looks like the PPA for Precise 12o4 (http://ppa.launchpad.net/pmcenery/ppa/ubuntu/dists/) no longer exist.

You need to either remove it or comment (#) it out in your software sources.list and/or your sources.list d. (http://www.googlubuntu.com/results/?cx=006238239194895611142%3Au-ocqbntw_o&cof=FORID%3A9&ie=UTF-8&q=how+to+edit+sources+list&as_qdr=all&sa=Google+Search&lang=en)

And welcome to the forum :)
