failed to verify repository GPG key

[spameden]

today I noticed something changed and there is no longer packages being
verified from nginx.org repository:

W: GPG error: http://nginx.org squeeze Release: The following signatures
were invalid: BADSIG ABF5BD827BD9BF62 nginx signing key <
signing-key at nginx.com>


did you guys change the key today?

i tried snatching key from http://nginx.org/keys/nginx_signing.key and from
PGP keyserver but still no luck same error appears
