Sahara Disk Image create Invocation Error

[Jai]

Configuration: Openstack Pike using devStack on Ubuntu16.04 VM

Plugins enabled during installation:
Sahara, Heat, Trove, Sahara Dashboard, Trove Dashboard

The install was successful and was able to access horizon.

Now, trying to build images for Sahara by following these steps:
Clone repository “https://github.com/openstack/sahara-image-elements” locally.
Use tox to build images.
When I run the command in the folder /sahara-image-elements
stack@devstack:~/sahara-image-elements$ tox -e venv -- sahara-image-create -u

Getting the following error

Any help appreciated....

Which image are you trying to build? With that command line the command should try to build all images for all distributions, which I'm not sure that we support properly. Can you please try to restrict the set of built images?

restricted to vanilla 2.7.1 and ubuntu, it worked. Thanks.
