Gpg: keyserver receive failed: no dirmngr

While trying to receive keys on my debian stretch server i get this error

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
Executing: /tmp/apt-key-gpghome.4B7hWtn7Rm/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.4B7hWtn7Rm/S.dirmngr' failed: No such file or directory
gpg: keyserver receive failed: No dirmngr

Installing the package dirmngr fixed the error.

user@debian-server:~$ sudo apt-get install dirmngr

Retrying .
