I have setup a blank VM and configured Ansible Tower via “.configure.sh” and answering the questions.  
After that I tried to install via “./setup.sh”

Playbook always fails at:

TASK: [postgres | determine if postgresql user exists] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
fatal: [coconut] =\> error while evaluating conditional: pg\_user\_exists.stdout != ‘1’

FATAL: all hosts have already failed – aborting

I’m using Ansible 1.9.3

I just installed Ansible the other day. I think you need to install postgresql separately.  
There are several steps during the install that the playbook doesn’t account for very well.

One package, can’t remember which, maybe postgres, i had to install it, then the installer uninstalled my version and installed its own.
