 dirmngr is a server for managing and downloading OpenPGP and X.509 certificates, as well as updates and status signals related to those certificates. For OpenPGP, this means pulling from the public HKP/HKPS keyservers, or from LDAP servers. For X.509 this includes Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol updates (OCSP). It is capable of using tor for network access.

+### RabbitMQ Server
+
+Installing RabbitMQ Server on Debian Stretch fails because the dependent packages `erlang-nox` and `esl-erlang` on Debian repos are slightly outdated. Hence, follow these instructions:
+
+Install [Erlang](#erlang) first.
+
+```shell
+# Add RabbitMQ repo from bintray to sources, but don't install it yet
+echo "deb https://dl.bintray.com/rabbitmq/debian stretch main" | sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list
+sudo apt update
+
+# Try installing erlang-nox
+sudo apt-get install erlang-nox
+
+# You might get this errors:
+# erlang-nox : Depends: erlang-diameter but it is not going to be installed
+#              Depends: erlang-eldap but it is not going to be installed
+# If you do so, try this:
+sudo apt-get install erlang-diameter erlang-eldap
+# Now this should install properly:
+sudo apt-get install erlang-nox
+
+# Now actually install RabbitMQ:
+sudo apt-get install rabbitmq-server
+```
+
+RabbitMQ Server should have automatically started by now, but if it is not, run `rabbitmq-server start` (sudo if required).
