Many lives ago, I created a GPG key to sign the Ubuntu Code of Conduct on Launchpad. I haven't really used it since. Some time later, I backed up my home and started fresh.
That was all back in 2009. I still have the backup but now I'm starting to play around with Quickly and upload things to Launchpad, I could really do with having my PGP key back.
I don't really know how the key is organised or where it's stored, but I'd like to recover my old key rather than generate a new one. Any idea where to start?
