git pull from the yun

Hi.

I am following these instructions to run a sample to send and receive messages from Azure IoT HUB :

I always get this response "fatal: Unable to find remote helper for 'https'" when I try to execute this line :

Using git instead https, this is the result:

Do I need to install something else to make it work?
