+```
+
+Explanation:
+
+When installing later releases of Ubuntu 16.04 (e.g., .3, .4, etc) a newer kernel
+is included. This kernel is set as the active kernel and will not work with the
+"tools" packages installed by following the earlier instructions. 
+
+To fix this, you have to either downgrade to the LTS kernel *or* install the "tools"
+packages for the active version of the kernel like so:
+
+1. `sudo apt-get update`
+1. `export running_kernel=$(uname -r); sudo apt-get install linux-tools-${running_kernel} linux-cloud-tools-${running_kernel}`
+1. `sudo reboot`
+
+Result:
+
+`ubuntu@ubuntu-1604-test:~$ dpkg -l | grep linux | grep -E "image|tools" | awk '{print $2, $3}' | sort`
