Found in: local machine (running chef-repo commit 218e29c3a8820c4cd168ba445805bcd5d506f760)

Priority: Medium (can run barbican just fine without Vagrant)

Severity: High

Description: barbican install during processing of "vagrant up" fails due to unavailable pre-reqs:

Reproduction steps:
1. First had to get around another issue by updating chef-repo/Berksfile.lock:
 find postgresql block and update these two sections:
      "locked_version": "3.2.1",
      "ref": "6d084b2c02332c0505e28df3458baf4c7ff14217"
2. run berks install to pick up that change
3. run vagrant destroy dbsimple (if this isn't a pristine environment)
4. run vagrant up
2. wait patiently for the failure

Expected Behaviour: barbican is up and running and ready for action

Observed Behaviour: server not available
