I’ve installed Ansible 1.2.3 on Ubuntu Precise 64.

Running `ansible-playbook -i ansible_hosts playbook.yml` give me this error:

```auto
ERROR: problem running ansible_hosts --list ([Errno 8] Exec format error)

```

Here’s the content of `ansible_hosts`:

```auto
[development]
localhost ansible_connection=local

```

and `playbook.yml`:

```auto
---
- hosts: development
  sudo: yes
  tasks:
    - name: install curl
      apt: pkg=curl update_cache=yes

```

How can I make this work?

Sounds like your INI file is marked executable and should not be, which is making ansible try to evaluate it as an external inventory script.

If I may make a request, please don’t ask questions on stack overflow and duplicate post them here, there is a infinitely larger community here and it just requires that we duplicate-post the answer and all the conversation, which is somewhat frustrating.

You were right. It works now.

I will use this group in the future. Also, I will answer with your answer on SO.

Thank you Michael.
