gpg, nginx, key

При установке nginx (doc) в debian 6 вылезает ошибка:

W: GPG error: http://nginx.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY ABF5BD827BD9BF62

Лечится так:

shell> gpg --keyserver hkp://keys.gnupg.net --recv-keys ABF5BD827BD9BF62
gpg: requesting key 7BD9BF62 from hkp server keys.gnupg.net
gpg: /root/.gnupg/trustdb.gpg: trustdb created
gpg: key 7BD9BF62: public key "nginx signing key " imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)
shell> gpg -a --export 7BD9BF62 | apt-key add -
OK
