+  Please install python-impacket in the correct Python environment.
+  At the moment the Python-based test servers still require Python 2.
+  Therefore you will need to use pip2 or your OS' package manager to
+  install the Python 2 version of impacket (if it is still available).
+
+  On stable Debian/Ubuntu the package name is "python-impacket".
+  On FreeBSD the package name is "py27-impacket".
