Hi,

I have tried to run molecule test for my Ansible role which contains install iptable dependencies. If I set hosts: localhost in converge.yml it is working fine. But if I give hosts: all throwing below error. I am using docker driver with ubuntu 18.04 installed on it to run my test.

TASK [twmn.twmn.iptable : Install dependencies] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
[WARNING]: Updating cache and auto-installing missing dependency: python3-apt  
fatal: [instance]: FAILED! =\> {“changed”: false, “cmd”: “apt-get update”, “msg”: “[Errno 2] No such file or directory: b’apt-get’: b’apt-get’”, “rc”: 2, “stderr”: “”, “stderr\_lines”: , “stdout”: “”, “stdout\_lines”: }

Anyhelp will be appreciable.

Thanks  
selvi
