Ansible : ERROR! SSH encountered an unknown error during the connection

Archives Ansible Project

Hi,

I am new the Ansible. I have setup ansible on Ubuntu machine as follows :

$ sudo apt-get update
$ sudo apt-get install software-properties-common
$ sudo apt-add-repository --yes --update ppa:ansible/ansible . ->> My machine don’t have internet connection so this command didn’t get executed
$ sudo apt-get install ansible

But machine show ansible is successfully installed

user@test-control-ansible:~$ ansible --version
ansible 2.0.0.2
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides

Then to verify I did simple ping test
I added target machine to ping to hosts file, added key-gen etc (I followed some online tutorial)

user@test-control-ansible:~$ ansible -m ping test-servers

test-ansible.target.9307289.com | UNREACHABLE! => {

“changed”: false,
“msg”: “ERROR! SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue”,
"unreach

Is this a problem because it failed to add PPA repository? If yes, then how to add PPA repository on offline(no internet connection) machine
OR Is this any other issue?
Please help me.

Thanks,
Nilesh

user@test-control-ansible:~$ ansible --version
ansible 2.0.0.2
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides

Because it installed the one in universe repo.
You can check with this command
   apt-cache policy ansible

2.0 is very old and not recommended to use.

Then to verify I did simple ping test
I added target machine to ping to hosts file, added key-gen etc (I
followed some online tutorial)

user@test-control-ansible:~$ ansible -m ping test-servers

test-ansible.target.9307289.com | UNREACHABLE! => {

    "changed": false,
    "msg": "ERROR! SSH encountered an unknown error during the connection.

debugging output to help diagnose the issue",

No. You would need to do as the error message say to find more clues to what is wrong.

If yes, then how
to add PPA repository on offline(no internet connection) machine
OR Is this any other issue?

Download the deb from PPA manually and transfer it to the offline machine and install it with "dpkg -i <some deb file>"

I have just 1-day experience on Ansible. Can you please tell me what deb package I have to download & from where?

Without knowing your Ubuntu version that would be impossible.

Its ubuntu version is xenial

user@test-conrol-ansible:~$ lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 16.04.6 LTS

Release: 16.04

Codename: xenial

This has nothing to do with Ansible since it's a generic Linux question, but here goes.

The PPA is here
https://launchpad.net/~ansible/+archive/ubuntu/ansible

In the upper right corner you'll see a link "View package details", when you click it you'll see a list of version.
Pressing on the link "ansible - 2.7.10-1ppa~xenial" under packages it will open a page where you find the deb link in bottom.
The link is https://launchpad.net/~ansible/+archive/ubuntu/ansible/+files/ansible_2.7.10-1ppa~xenial_all.deb
