Native installation for Juniper

I followed the instructions in installing Open edX with Native installation as a guide.
It works with Ironwood version without errors, but on Juniper the installation of Open edX returned an error with Ansible failed.

Site reference:

use juniper.master instead.

Thanks for the info.
Installation completed.
