Ansible Failed to set permissions on the temporary - ansible

Question

I am using ansible to replace the ssh keys for a user on multiple RHEL6 & RHEL7 servers. The task I am running is:
- name: private key
copy:
src: /Users/me/Documents/keys/id_rsa
dest: ~/.ssh/
owner: unpriv
group: unpriv
mode: 0600
backup: yes
Two of the hosts that I'm trying to update are giving the following error:
fatal: [host1]: FAILED! => {"failed": true, "msg": "Failed to set
permissions on the temporary files Ansible needs to create when
becoming an unprivileged user (rc: 1, err: chown: changing ownership
of /tmp/ansible-tmp-19/': Operation not permitted\nchown: changing
ownership of/tmp/ansible-tmp-19/stat.py': Operation not
permitted\n). For information on working around this, see
https://docs.ansible.com/ansible/become.html#becoming-an-unprivileged-user"}
The thing is that these two that are getting the errors are clones of some that are updating just fine. I've compared the sudoers and sshd settings, as well as permissions and mount options on the /tmp directory. They are all the same between the problem hosts and the working ones. Any ideas on what I could check next?
I am running ansible 2.3.1.0 on Mac OS Sierra, if that helps.
Update:
#techraf
I have no idea why this worked on all hosts except for two. Here is the original playbook:
- name: ssh_keys
hosts: my_hosts
remote_user: my_user
tasks:
- include: ./roles/common/tasks/keys.yml
become: yes
become_method: sudo
and original keys.yml:
- name: public key
copy:
src: /Users/me/Documents/keys/id_rsab
dest: ~/.ssh/
owner: unpriv
group: unpriv
mode: 060
backup: yes
I changed the playbook to:
- name: ssh_keys
hosts: my_hosts
remote_user: my_user
tasks:
- include: ./roles/common/tasks/keys.yml
become: yes
become_method: sudo
become_user: root
And keys.yml to:
- name: public key
copy:
src: /Users/me/Documents/keys/id_rsab
dest: /home/unpriv/.ssh/
owner: unpriv
group: unpriv
mode: 0600
backup: yes
And it worked across all hosts.

Answer 1

Try to install ACL on remote host, after that execute ansible script
sudo apt-get install acl

Answer 2

You could try something like this:
- name: private key
become: true
become_user: root
copy:
src: /Users/me/Documents/keys/id_rsa
dest: ~/.ssh/
owner: unpriv
group: unpriv
mode: 0600
backup: yes
Notice the:
become: true
become_user: root
Check the "become" docs for more info

Answer 3

While installing the acl module works there is an alternative.
Add the line below to the defaults section of your ansible.cfg.
allow_world_readable_tmpfiles = True
Of better, just add it to the task that needs it with:
vars:
allow_world_readable_tmpfiles: true

Answer 4

I'm using ad-hoc and when I got into this problem, adding -b --become-user ANSIBLE_USER to my command fixes my problem.
example:
ansible all -m file -a "path=/etc/s.text state=touch" -b --become-user ansadmin
Of course, before this, I had given Sudo access to the user
If you give Sudo access to your user, you can write like this :
ansible all -m file -a "path=/var/s.text state=touch" -b --become-user root
