Ansible error's

• 2020-09 [WARNING]: Unable to parse <file> as an inventory source

  • Debug with

    ansible --list-hosts all -i <file> -vvv

    • error seen "Skipping due to inventory source not existing or not being readable by the current user"
    • Apparently ansible tries to parse inventory files with different plugins, ini, yaml, etc.
