Hello,

I've got a big problem with my GPG key pair: The secret key doesn't show
a user id any more!
After accidentially copying pubring.gpg~ over pubring.gpg the following
mismatch between the private & public key appeared:

joerg@norad:~/.gnupg > gpg --list-secret-key
/home/joerg/.gnupg/secring.gpg
------------------------------
sec  1024D/68FBD67F 2000-01-18 
ssb  1024g/CB70CD4D 2000-01-18

However the public key has still its UID:

/home/joerg/.gnupg/pubring.gpg
------------------------------
pub  1024D/68FBD67F 2000-01-18 Joerg Ziefle <joerg.ziefle@gmx.de>
sub  1024g/CB70CD4D 2000-01-18

Unfortunately, I can't revoke the key pair (secret key not found).
But if creating a new key pair with the same user id, 

gpg --list-keys 68FBD67F

says: secret key available, and it uses the secret key of the new key
pair (is this a bug in GPG?). I can even create a revocation certificate
(using the passphrase of the old secret key, hm...), but the server
doesn't accept it.

What now?

Joerg
