This question already has an answer here:

I added a PPA for updating my kernel for ubuntu-12.04. Later, I found that the kernel doesnot exist on the link within PPA.

I used this command. sudo add-apt-repository ppa:kernel-ppa/ppa

Now if I try sudo apt-get update, I get an error 404, because http://ppa.launchpad.net/kernel-ppa/ppa/ubuntu/dists/precise/main/source/Sources, does not exist.

Trouble is I am unable to do an update. Even not able to do sudo ppa-purge ppa:kernel-ppa/ppa

Suggest a solution.
