GPG Fetch key failed: gpg: keyserver receive failed: End of file

Environment:
macOS: 10.13.1

How did I install the gpg:
$ brew install gnupg gnupg2

GPG version:

$ gpg --version
gpg (GnuPG) 2.2.3
libgcrypt 1.8.1

Tried with "hkp://pgp.mit.edu" also got the same error:

I also tried:

    gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

or if it fails:

    command curl -sSL https://rvm.io/mpapis.asc | gpg --import -

the key can be compared with:

    https://rvm.io/mpapis.asc
    https://keybase.io/mpapis

NOTE: GPG version 2.1.17 have a bug which cause failures during fetching keys from remote server. Please downgrade or upgrade to newer version (if available) or use the second method described above.

But when I trying gpg2 I got:

$ gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
-bash: gpg2: command not found

[mpapis]

not sure why gpg2 is not available, but gpg points to V2 (probablythanks to bin.install_symlink "gpg2" => "gpg")

please try:

gpg --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

Hi @mpapis!

I tried running the mentioned command, but I got this error message:

$ gpg --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
gpg: keyserver receive failed: No route to host

I installed gpg2 through brew:
brew install gpg # this installs gpg2 version 2.2.10

I also tried installing without checking the signature, but the check is automated, so that failed as well:

(gpg2 is "command not found", like above)

This finally worked:

$ curl -sSL https://rvm.io/mpapis.asc | gpg --import -
