not working with salt-cloud shows unknown locale error

[AmitChotaliya]

I am using salt-cloud to create instances and passing a specific version for salt-minion as script argument.

staging2-frontline:
  provider: aws
  image: ami-408c7f28
  size: m1.small
  securitygroup:
    - Staging-Global
    - Staging-FrontLine
  tag:
      circle: staging2
      type: frontline
  script: bootstrap-salt
  script_args: stable 2015.5

I am getting the following error.

* ERROR: salt-minion was not found running
 * ERROR: Failed to run daemons_running()!!!

I even tried without passing any script args and it still does not work. I used it without passing any script args a month back It worked then.
