Hello. I failed to build the docker image due to the gpg: keyserver receive failed: No name error during gpg verification. I saw a PR #575 try to fix it by removing the verification but it was declined. As nodejs/docker-node#1500 said, the actual reason is the sks-keyservers.net is never available to verify gpg keys. keyserver.ubuntu.com and keys.opengpg.org are good alternatives. I succeed to pass the validataion with these two servers.
