Environment

• Platform: debian
• Docker Version: 20.10.6
• Node.js Version: 12, 14, 16
• Image Tag: n/a

Expected Behavior

Building image succeeds.

Current Behavior

Building fails due to failure to fetch GPG keys. The errors look like this:

gpg --batch --keyserver hkp://ipv4.pool.sks-keyservers.net --recv-keys 94AE36675C464D64BAFA68DD7434390BDBE9B9C5
gpg: keyserver receive failed: No name

And then later on you get a gpg: keyserver receive failed: No keyserver available.

Some keys succeed if they're mirrored at pgp.mit.edu, but all keys that are only hosted on sks-keyservers.net will fail to download. https://sks-keyservers.net explains why:

Update 2021-06-21: Due to even more GDPR takedown requests, the DNS records for the pool will no longer be provided at all.

Possible Solution

• Use a specific keyserver directly instead of pool address
• Get Node releasers to permit their user IDs be hosted on keys.openpgp.org (otherwise the key can't be received by gpg)

Steps to Reproduce

docker build 16/buster-slim, but I assume this affects all Dockerfiles.

Additional Information

Fixing Nodejs release key distribution is tracked in nodejs/admin#456 and its linked issues.
