Entering the wrong PPA (Private Package Repository) in the Ubuntu Terminal results in a 404 Not Found error. This error can result in the slow down of the apt-get update and seems pretty annoying. Fix404 PPA is a script which disables the PPAs that cause 404 Not Found errors. It provides the convenience of not having to disable faulty PPAs from Software Sources. Fix 404 PPAs checks for 404 messages for PPAs and alerts you to disable them.
Fix 404 can be installed in Ubuntu 11.04 Natty by entering the following commands in the Terminal:
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 downloaded from the Launchpad link given at the end of this post. If you would like to try out a software which can help you easily search and add application PPAs from Launchpad, then check out YPPA Manager.
Get rid of those PPAs which cause the annoying 404 Not Found error messages on apt-get updates now.
