Q: Reproducible Environments for Scientific Application: "Problem: SSH policy file is empty?"

When I get to the Run a Virtual Machine section of the "Using Nimbus" tutorial (http://archive.futuregrid.org/tutorials/nimbus) I get this:

[rruuww@login1 nimbus-cloud-client-021]$ bin/cloud-client.sh --conf conf/hotel.conf --run --name hello-cloud --hours 2

Launching workspace.

Workspace Factory Service:
    https://svc.uc.futuregrid.org:8443/wsrf/services/WorkspaceFactoryService


Problem: SSH policy file is empty?
See help (-h).

Problem running 'vm-006'.

I have deleted, recreated and reload my ssh keys already.

How should I proceed?

Cheers
