Comment 2 for bug 1736859

I am able to reproduce the same issue.
Just before the task to deploy undercloud, I addeda task to sleep for a minute and logged into the undercloud VM and created the undercloud-install.sh myself. undercloud install was succcesful. But later failed because some overcloud-prep-*.sh file was missing. Looks like the roles/undercloud-deploy/create-script.yaml playbook is not called at all
