Ansible synchronize module error - no tty present and no askpass program specified

Question

ubuntu 14.04.3 LTS ansible version: 2.1.0, the sshport on remote server is 44022

Im using adhoc way to run synchronize module as a sudo user[nopasswd is not enabled] to synchronize local and remote directories (push)

Below is host file /etc/ansible/hosts

[webdb]
10.153.99.132
10.153.99.52
[webdb:vars]
ansible_ssh_user=ctuser
ansible_ssh_private_key_file=/root/.ssh/id_rsa
ansible_port=44022

Below are the command used:

ansible webdb -s -K  -m synchronize -a "src=/tmp/muhan 
dest=/store" -u ctuser

and (dest_port used)

ansible webdb -s -K  -m synchronize -a "dest_port=44022 
src=/tmp/muhan dest=/store" -u ctuser

Both commands outputs below error:-

-s and -K are both deprecated. What do you get if you use -b and --ask-become-pass? — MillerGeek
Also, if you are using key-based authentication it may be ideal to enable passwordless sudo. — MillerGeek

You can tackle this from multiple angles:

disable sudo tty requirement: sed -i 's/Defaults requiretty/Defaults !requiretty/g' /etc/sudoers (this is on all of the nodes you are using Ansible)
change ansible.cfg to have tty flag for ssh http://docs.ansible.com/ansible/intro_configuration.html#ssh-args (this is only on the node where you are executing Ansible on)

The exact switches you need:

ssh_args = -tt

Ansible synchronize module error - no tty present and no askpass program specified
