The old key is obsolete.
I imported your new gpg key into the keyring; but it's rather unclear to me how to change it on your account; following:
I don't see how ud-user -r -u lets you change the GPG key. I'll poke Tollef.
Also - given that it is the ssh key that gives you access to a git push - are you sure you don't want to change that instead ? :-) Finally if you want me to store a pass-phrase protected public/private key for you that's easy to do.
