You don't need a public key to suppress this warning. The reason gpg is
warning about the validity of this key is that when gpg exports keys,
the ownertrust information, which is kept in ~/.gnupg/trustdb.gpg, isn't
exported with the key. When you imported the keys onto your server, gpg
didn't import any ownertrust information.
If you created a signing key (we'll call it AABBCCDD) and signed your
key 12345678 with AABBCCDD, gpg wouldn't trust the signature unless it
trusted the owner of the key (ownertrust). The answer lies in fixing
the ownertrust.
You need to edit the key with the following commands.
gpg --edit-key 12345678
trust
Gpg will ask how much trust to give. Choose 5, which is ultimate,
because you own the secret key.
