Cannot create template with error "The server has either errd or incapable..."

Cannot create a template based on the tutorial https://wiki.openstack.org/wiki/Meteos/ExampleLinear

Not sure if this is my devstack issue but would request someone to verify it.

Steps:
 1. Install meteos on Devstack following this tutorial https://wiki.openstack.org/wiki/Meteos/Devstack
 2. Try creating a template

Result:
 Following error: (Same thing happens on the GUI as well)
ERROR: The server has either erred or is incapable of performing the requested operation.
