Hi TDE friends,

I am installing the new Debian Stretch on my computer, with
preliminary stable builds repo.
When i try to download the GPG key, i get this error :

root@nibelheim:/home/dobigeon# apt-key adv --keyserver keys.gnupg.net
--recv-key A04BE668

Executing: /tmp/apt-key-gpghome.MwJokQaOGB/gpg.1.sh --keyserver
keys.gnupg.net --recv-key A04BE668
gpg: failed to start the dirmngr '/usr/bin/dirmngr': Aucun fichier ou
dossier de ce type
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.MwJokQaOGB/S.dirmngr'
failed: Aucun fichier ou dossier de ce type
gpg: keyserver receive failed: Pas de dirmngr

A problem with the GPG key ? Or the command line on the wiki page (
https://wiki.trinitydesktop.org/Preliminary_Stable_Builds ) ?

Thanks for your help.
