[tor-relays] Debian9 install gpg repository problem

Hey!

I've set up quickly a Debian9 on a Windows Virtualbox.

When trying to follow the guide here "Option two: Tor on Ubuntu or Debian" https://www.torproject.org/docs/debian.html.en#ubuntu

The first command line result is (root account used) :

# gpg --keyserver keys.gnupg.net --recv A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 gpg: failed to start the dirmngr '/usr/bin/dirmngr': Aucun fichier ou dossier de ce type gpg: connecting dirmngr at '/root/.gnupg/S.dirmngr' failed: Aucun fichier ou dossier de ce type gpg: keyserver receive failed: Pas de dirmngr
