Find or recreate a revocation certificate, then merge and publish, see

https://gnupg.org/documentation/manuals/gnupg/OpenPGP-Key-Management.html#index-generate_002dkey

On the command line it would be a
  gpg --send-keys  KEY_ID
command.

The old network and pools of public keyservers have broken down,
a new one is emerging but does not (yet) have all features, see

https://spider.pgpkeys.eu/sks-peers lists almost 50,
not all functional. There are more, some do not sync with others,
some violate the OpenPGP standard.

Best Regards,
Bernhard
