Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/570

Describe the bug
Running self-hosting deployment on CentOS 7.7 results in the following error:

fatal: [localhost]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'stdout'"}

To Reproduce
Steps to reproduce the behavior:

Clone the repo to /opt/
Run the playbook with ansible-playbook -i inventory site.yml
See error:

TASK [netbootxyz : Generate ipxe disk checksums] *****************************************************************
changed: [localhost]

TASK [netbootxyz : Generate site name banner for index] **********************************************************
skipping: [localhost]

TASK [netbootxyz : Generate netboot.xyz index template] **********************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'stdout'"}

Quick Fix
There is an issue jinja template for index.html.j2 at line 27:

{% if index_title is defined %}
  {{ index_title.stdout }}
  {% else %}
  <h1>{{ site_name }}</h1>
  {% endif %}

index_title variable is defined even when the task is skipped but missing stdout key - see debug for index_title variable:

TASK [netbootxyz : Generate site name banner for index] **********************************************************
skipping: [localhost]

TASK [netbootxyz : debug] ****************************************************************************************
ok: [localhost] => {
    "index_title": {
        "changed": false,
        "skip_reason": "Conditional result was False",
        "skipped": true
    }
}

TASK [netbootxyz : Generate netboot.xyz index template] **********************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'stdout'"}

The if statement should look as follows:

 {% if index_title.stdout is defined %}
  {{ index_title.stdout }}
  {% else %}
  <h1>{{ site_name }}</h1>
  {% endif %}
