HHVM - gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory

Hi All,
I'm setting up ISP Config on Debian 9 via this tutorial:
https://www.howtoforge.com/tutorial...-8-4-jessie-apache-bind-dovecot-ispconfig-3-1

I get to step 10.1 Install HHVM (HipHop Virtual Machine) and I get the following output:

Code:

root@ISP-Config-2:/# apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xB4112585D386EB94
Executing: /tmp/apt-key-gpghome.53FCWKiapx/gpg.1.sh --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xB4112585D386EB94
gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.53FCWKiapx/S.dirmngr' failed: No such file or directory
gpg: keyserver receive failed: No dirmngr
root@ISP-Config-2:/#

Can someone please explain to me what has happened here? What went wrong? And what to do about it. I notice "ubuntu" in the URL, is this an error in the tutorial?
Thanks very much!

 

Everybody just RELAX! I figured it out, it's an error in the tutorial.
Debian 9 no longer comes with dirmngr so we need to install it using:

Code:

sudo apt-get install dirmngr --install-recommends

then just keep calm and continue programming...
