Newbie question: Error message from ansible ping module

[Henrik Bach]

Hi, 

I'm new to Ansible.

I've installed ansible on my ubuntu 16.04: 

$ ansible --version

ansible 2.0.0.2

  config file = /etc/ansible/ansible.cfg

  configured module search path = Default w/o overrides

When I try to test whether ansible is able to connect with my test node, I get this error:

$ ansible all -i hosts -m ping -u sad -vvvvvv

Using /etc/ansible/ansible.cfg as config file

Loaded callback minimal of type stdout, v2.0

I guess you test node is also Ubuntu 16.04?

The ping module need Python 2 on the node.
Default Ubuntu 16.04 only install Python 3, install the package "python"
on you test node and it should work.
