Hello,

I have spend a lot of time to find a solution at this issue.  
I have a task :

`

- name: check updated package (Debian)  
command: apt-get -s install {{ item.item }}  
register: updateD  
when: (ansible\_os\_family == “Debian”) and (installD is defined) and ( {{ item.rc }} == 0)  
with\_items: “{{ installD.results }}”  
failed\_when: updateD \> 1  
changed\_when: no  
`

and Ansible reaction is :

[WARNING]: Consider using apt module rather than running apt-get

But I don’t find any option in documentation to obtain the result of “-s”.

Hi,

Could you explain what you want to do ?  
To not do things in ansible but simulate, there’s --check command line option

Regards,

JYL

The result of the command is registered in the variable updateD

> &nbsp;&nbsp;when: (ansible\_os\_family == "Debian") and (installD is defined) and ( {{  
> item.rc }} == 0)

You should not use {{ }} in when, they are implied.

> &nbsp;&nbsp;with\_items: "{{ installD.results }}"  
> &nbsp;&nbsp;failed\_when: updateD \> 1  
> &nbsp;&nbsp;changed\_when: no

Since they are in the variable updateD you can print out all of them like this.

- debug: var=updateD

I want to check if a package need to be updated and write a log file. That why i use apt-get -s install, and I put the result with a register to use it later.

Thanks for watching my problem.
