Re: [ansible-project] [WARNING]: Unhandled error in Python interpreter....

[bill paxton]

Thank you.  I did open an ansible github issue 
 and subsequently closed 
it based on respondents there.  Your comments above definitely helped.  
Seems 2.9.10 fixed "buggy behavior" that I was relying on by not explicitly 
using "connection: local".

FWIW, I'm still on 2.9.6.

As a hint, try to find out why *ssh* connection plugin is used to
connect localhost. IMHO, the default is *local*. For example, testing
with no configuration of the connection ("cat hosts | grep
connection" shows nothing)

  shell> cat pb.yml
  - hosts: test_01
tasks:
  - debug:
  var: ansible_connection
  - debug:
  var: ansible_connection
delegate_to: localhost

gives

  TASK [debug] 
  ok: [test_01] =>
ansible_connection: ssh

  TASK [debug]
  ok: [test_01 -> localhost] =>
ansible_connection: local

See DEFAULT_TRANSPORT
https://docs.ansible.com/ansible/latest/reference_appendices/config.html#default-transport

"man ansible" says

  -v, --verbose
  verbose mode (-vvv for more, - to enable connection
  debugging)

For example

  shell> ansible-playbook pb.yml - | grep connection
  connection: smart
ansible_connection: ssh
ansible_connection: local

[ansible-project] [WARNING]: Unhandled error in Python interpreter....

[bill paxton]

I have a task that works fine for Ansible 2.9.7, but fails when I upgrade 
to 2.10.3.

```
yaml
- name: Ping ServiceNow IP Address
  shell: "ping -c 1 -w 5 {{ sn_ip_address | trim }}"
  ignore_errors: true
  register: ping_result_sn_ip_address_raw
   when: sn_ip_address | trim | ipv4
   failed_when: false
   changed_when: false
   delegate_to: localhost
```

When the task is run with Ansible 2.10.3, I receive:

[WARNING]: Unhandled error in Python interpreter discovery for host
some_snow_host: Failed to connect to the host via ssh: ssh: connect to host
localhost port 22: Cannot assign requested address
fatal: [some_snow_host]: UNREACHABLE! => {
"changed": false,
"unreachable": true
}

MSG:

Data could not be sent to remote host "localhost". Make sure this host can 
be reached over ssh: ssh: connect to host localhost port 22: Cannot assign 
requested address

*Note:* there are other tasks in the same playbook that use "delegate_to: 
localhost" that work fine, although those tasks are not using the "shell" 
module.
