Open Stack

Hello Asha,

It seems like your installer script might be crashing for some reason. You might need to execute the steps in the installer script manually to stand things up, such as the pip install step here: https://github.com/openstack/barbican/blob/master/bin/barbican.sh#L87

Please let us know if that helps.

Thanks,
John
