Desired Behavior

Followed the following document https://www.digitalocean.com/community/tutorials/how-to-test-ansible-roles-with-molecule to install, test molecule on an Ubuntu 16.04 VM running in VirtualBox.

When I ran molecule test I got an error when it was building the docker instance. A re-run with --debug gives me this error:

Please ignore.

It was a lucky search but I found this issue: https://github.com/metacloud/molecule/issues/1353 following it I removed docker-py and installed docker via pip. That fixed my problem.

Thanks,
Louis
