Answer 1

Looks like gpg cannot fetch the keys, maybe the servers are down, whatever. Try to replace the value of --keyserver specified in the Dockerfile with hkps://keys.openpgp.org .

I took the URL from here: https://github.com/nodejs/node#release-keys

Change this:

gpg --batch --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys "$key"

to this:

gpg --batch --keyserver hkps://keys.openpgp.org --recv-keys "$key"

and remove the following two commands that try using other two servers.
