Ansible and `uname -r` or $(uname -r) runs on localhost. Why?

Question

linux

Faced such a bug (or feature?):
when trying to execute the command

ansible group01 -m apt -s -a "name=linux-headers-`uname -r` state=present"

or

ansible group01 -m apt -s -a "name=linux-headers-$(uname -r) state=present"

I receive in response:

hostXXX | FAILED >> {
    "failed": true,
    "msg": "No package matching 'linux-headers-16.1.0' is available"
}

I 'm running under Mac OS X.
Ansible version 1.9.3
on the remote host uname -r shows:

4.2.0-42-generic

if I execute uname -r in the terminal

16.1.0

Why is that? And how to fix it?

Answer 1

There was a discussion, but someone deleted it, they suggested a solution:
Melkij left a comment on the answer to the Ansible question and `uname -r` or $(uname -r) works on the local host. Why?
As a result, it turned out to be like this:

ansible a-install -m raw -s -a "apt install -y linux-headers-$(uname\ -r)"

Answer 2

'uname=linux-headers-`uname -r` state=present'
in 'single' quotes, or escape \`
