Revoking a Lost OpenPGP Key From Ubuntu Servers

[gerowen]

So back in 2011 I generated an OpenPGP key to use for encrypting files/emails and digitally signing things.

The computer I used to generate that key is long gone (I used it for target practice because it kept overheating), and I'm not quite sure how I would go about revoking that old key, so I generated a new one on this computer to start using and have sync'd it with the Ubuntu servers as well. However, I've noticed my old one is still there. I was wondering if anybody could help me out.

My new key, and the one I want to remain on the server has the following information:
Key ID: BAFDBD15

The old key, and the one I want to be removed from the server, has the following information:
Key ID: 257503EF

I've updated my Launchpad account to use the new key as well, but I want to make sure that anybody who sends me an e-mail uses the correct key to encrypt things.

You can not remove the old key, you can only revoke it

This link might also help you to revoke it or at least to add some information, so that people might understand, that it does not work any more.
