Using Ansible 2.4.2.0 on Ubuntu 16.04, I try running a plaubook with the following:

- name: Create repo line in Ubuntu/Debian  
command: bash -c "echo "deb [arch=amd64] [https://download.docker.com/linux/debian](https://download.docker.com/linux/debian) $(lsb\_release -cs) stable" "  
register: docker\_repo\_line  
when:  
ansible\_distribution == ‘Debian’  
or  
ansible\_distribution == ‘Ubuntu’
- debug:  
msg: “{{ docker\_repo\_line.stdout }}”  
when:  
ansible\_distribution == ‘Debian’  
or  
ansible\_distribution == ‘Ubuntu’
- name: Add Docker Repo on Ubuntu/Debian  
apt\_repository:  
repo: “{{ docker\_repo\_line.stdout }}”  
state: present  
when:  
ansible\_distribution == ‘Debian’  
or  
ansible\_distribution == ‘Ubuntu’

However, the Debig Module set the message as “hello, world” when I run the command. Looking at the module documentation, this is the default if no msg is specified. However, I do I have line for hte message. Am I missing something here?

My guess is all the module results are contained in a key called 'results' within the var that you registered.

Try this

- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var: "{{ docker\_repo\_line }}"

I suspect that the bit you want is in  
- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ docker\_repo\_line.results.stdout }}"

But try inspecting the whole of the var. If there is a lot of output, use something like Jsonlint.com to pretty print the json so that you can get a clearer idea of what is being returned.

Hope this helps,

Jon
