On VirtualBox, you may need to install rng-tools to generate enough entropy for GPG keys (otherwise the generation will be very slow):

.. code-block:: bash

    sudo apt-get install rng-tools
    echo "HRNGDEVICE=/dev/urandom" | sudo tee -a /etc/default/rng-tools
    sudo service rng-tools restart
{% endblock %}
