When creating a machine with the following userdata:

#cloud-config
chpasswd:
  list: |
    ubuntu:passw0rd
ssh_pwauth: True

cloud-init will fails if the machine does not have openssh installed on it. That happens because pasasword module will try to run the following command:

service ssh restart

Which will fail if the machine does not have openssh installed.

How to reproduce:

Just launch an lxd vm with the provided userdata using the following image as base: images:ubuntu/16.04/cloud
