Hello,

As a learning exercise I am trying to install OpenStack Newton on Ubuntu 16.0.4.1 LTS. I am following the documentation located here: http://docs.openstack.org/newton/inst...

Unfortunately I am stuck early in the process, at the first service to be installed, keystone. Specifically, verifying its installation. All steps before that went without error. However, at this page of the doc- http://docs.openstack.org/newton/inst... - I am getting errors when trying to execute the OpenStack create commands on this page. For example:

   openstack project create --domain default   --description "Service Project" service

Results in

Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL.

Internal Server Error (HTTP 500)

These errors are in the /var/log/apache2/keystone.log:
