How to remove a key from keyserver?

[Bahman Movaqar]

Hi all,

I, mistakenly, generated several keys, sent them to 'subkeys.pgp.net'
and deleted the ~/.gnupg directory while I _had not_ generated a
revocation certificate for any of those keys except one.

Now my question is:
Since all of the keys are for the same email address, how can I remove
redundant keys and leave out only one?

Any idea/suggestion is appreciated.

If there are no known vulnerabilities, the system must be secure. If
there is a vulnerability, then once it's fixed, the system is again
secure. How anyone comes to this presumption is a mystery to me.
