Как исправить ошибку The task includes an option with an undefined variable в Ansible?

Добрый день.

Помогите разобраться с Ansible новичку. Есть вот такой простой playbook найденный на просторах интернета:
---
- hosts: test
tasks:

- name: Debug
debug:
msg={{ ansible_os_family }}

- set_fact: package_name=httpd
when: ansible_os_family == "Redhat"

- set_fact: package_name=apache2
when: ansible_os_family == "Debian"

- name: Install httpd package
yum: name={{ package_name }} state=latest
when: ansible_os_family == "Redhat"

- name: Debug1
debug: msg={{ package_name }}

- name: Install apache2 package
apt: name={{ package_name }} state=latest
when: ansible_os_family == "Debian"

выполнение которого завершается ошибкой:

полагаю что тут проблема в синтаксисе, но никак не могу понять что нужно исправить...

Redhat и RedHat - это две большие разницы :)
