unable to install apache using Ansible-playbook

[hit-monchan]

I am a beginner in terraform and ansible. I am following the linuxacademy course to deploy a wordpress website using terraform and ansible in an aws enviroment.

Course reference : https://github.com/linuxacademy/terransible/tree/master/course_scripts

My setup: OS version : Ubuntu Server 16.04 ansible version : 2.4.2.0 python version 2.7.12

After went through alot of troubleshooting, I am able to run terraform apply successfully.

When i run ansible-playbook -i aws_hosts wordpress.yml, i encounter this error

TASK [Install Apache.] *******************************************************************************************************
failed: [111.22.22.22] (item=[u'httpd', u'php', u'php-mysql']) => {"changed": false, "item": ["httpd", "php", "php-mysql"], "msg": "No package matching 'httpd' found available, installed or updated", "rc": 126, "results": ["No package matching 'httpd' found available, installed or updated"]}

Here is my wordpress.yml config file
