How do I receive keys from keyservers, with GnuPG 2?
The GnuPG FAQ document recommends I use
pool.sks-keyservers.net for the keyserver. That has worked for a long time in GnuPG 1, but in GnuPG 2:
$ gpg2 --keyserver pool.sks-keyservers.net --recv-keys DECAFBAD gpg: keyserver receive failed: Invalid argument
What does “Invalid argument” mean? Which argument, and what validation failed?
$ gpg2 --version gpg (GnuPG) 2.1.15 libgcrypt 1.7.3-beta
How do I use
gpg2 to receive a key from the keyserver network?
