Hi Werner,

It's Linux 3.10.0-229.4.2.el7.x86_64 and GnuPG 2.0.22 libgcrypt 1.5.3.
If you mean the commands to delete the test secret key that is now somehow
still showing up when I try to delete the new public key, just imported,
that's:
gpg --delete-secret-keys 'user ID...'

Trying to edit the newly imported key:
gpg -u 'user ID for the key that is used to sign/trust keys' --edit-key
'user ID of the new key'
also tried
gpg -u 'user ID for the key that is used to sign/trust keys' --edit-key
keyID...

I hope this helps, thanks.
Raf
