+.. note:: The following applies to Ubuntu 16.04 users only.
+
+By default Ubuntu 16.04 comes with Python 3.5.1 installed as the ``python3`` binary.
+The Fabric Node.js SDK requires an iteration of Python 2.7 in order for ``npm install``
+operations to complete successfully.  Retrieve the 2.7 version with the following command:
+
+.. code:: bash
+
+  sudo apt-get install python
+
+Check your version(s):
+
+.. code:: bash
+
+  python --version
