Trouble provisioning remote server with ansible 2.4

Hi roots community, I have another frustrating dilemma and it would be wonderful to have another pair of eyes on this (really any but mine…). I get this error when I try to provision the remote server (even with the --ask-pass option… same error without the option as well).

$sudo ansible-playbook server.yml -e env=staging -u root --ask-pass -vvvv

root@159.65.244.133: Permission denied (publickey).

fatal: [159.65.244.133]: UNREACHABLE! => {
    "changed": false, 
    "unreachable": true
}

This is the error that outputs when I run ansible ping

$ ansible staging -m ping -u root --ask-pass

SSH password:

    "module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n", 
    "msg": "MODULE FAILURE",

}

You may notice it complains about not finding /usr/bin/python, but that file /is / there :c

Let me know if there is any more detail I can provide.
I’m running out of tricks! Please help! Thank you for your advice and assistance!

Why are you running ansible as root? I’m not sure why that would be necessary, and it seems kind of dangerous (and like it could be causing your issue).

At the risk of stating the obvious, it looks like you haven’t loaded an SSH key. The docs have some details on using SSH keys: https://roots.io/trellis/docs/ssh-keys/ I don’t know if Trellis is written to work without SSH keys.
