Hi Vishwas,

Without looking at logs and playbooks used, it is very difficult to tell what is wrong. Please provide details about background, roles used, a snippet of playbook failing, console log of the run, debugging steps taken, etc.

> &nbsp;&nbsp;when: "{{ disable\_service\_controls|  
> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;default(false) }}" == false

See "The When Statement"  
[https://docs.ansible.com/ansible/latest/user\_guide/playbooks\_conditionals.html#the-when-statement](https://docs.ansible.com/ansible/latest/user_guide/playbooks_conditionals.html#the-when-statement)  
" ... which contains a raw Jinja2 expression without double curly braces."

Try this playbook

&nbsp;&nbsp;\> cat pb.yml  
&nbsp;&nbsp;- hosts: localhost  
&nbsp;&nbsp;&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: Disabled  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: disable\_service\_controls|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;default(false)|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;bool  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- set\_fact:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;disable\_service\_controls: true  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: Disabled  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: disable\_service\_controls|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;default(false)|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;bool

It will skip the first debug. (Gives abridged)

&nbsp;&nbsp;TASK [debug] \*\*\*\*  
&nbsp;&nbsp;skipping: [localhost]  
&nbsp;&nbsp;TASK [set\_fact] \*\*\*\*  
&nbsp;&nbsp;ok: [localhost]  
&nbsp;&nbsp;TASK [debug] \*\*\*\*  
&nbsp;&nbsp;ok: [localhost] =\> { "msg": "Disabled" }

Use "bool" filters. See "Bare variables in conditionals"  
[https://docs.ansible.com/ansible/latest/porting\_guides/porting\_guide\_2.8.html#bare-variables-in-conditionals](https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.8.html#bare-variables-in-conditionals)  
" ... update your conditional statements so they accept only boolean values."

In addition to this, try --extra-vars. Extra vars pass the values always as  
strings. The explicit conversion to boolean is necessary.

&nbsp;&nbsp;\> ansible-playbook pb.yml -e "disable\_service\_controls=true"

HTH,

&nbsp;&nbsp;-vlado

No. It does not. This one (in the previous email) looks good

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: disable\_service\_controls|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;default(false)|
