Entering the wrong PPA in the Ubuntu Terminal window results in a 404 Not Found error. This error can slow down apt-get updates and seems quite irritating. Fix404 PPA is a script which disables such PPAs which cause the 404 Not Found error. It provides the convenience of not having to manually disable defective or incorrect PPAs from Ubuntu Software Sources. Fix 404 PPAs checks for 404 messages from PPAs and alerts you to disable the ones which cause a 404 error..
Fix 404 can be installed in Ubuntu 11.04 Natty by entering the following Terminal commands:
sudo apt-add-repository ppa:lkjoel/fix404 sudo apt-get update sudo apt-get install fix404
If you are using a pre-Natty version, a Deb package can be acquired from the Launchpad link given at the end of this post. You can also try out YPPA Manager which allows adding Launchpad PPAs by searching out an application’s name.
