handshake failed: ssh: unable to authenticate, attempted methods [none password keyboard-interactive], no supported methods remain

问题

The problem in this question resembles SSH failed when building RancherOS with Packer

However, the behavior of my Packer is different. I get

==> virtualbox-iso: Error waiting for SSH: ssh: handshake failed: ssh:
unable to authenticate, attempted methods [none password keyboard-
interactive], no supported methods remain

I am not sure why Packer is not able to ssh into the VM. I can see VirtualBox Console Screen sits on a login input. Then it timeouts and gets discarded by packer's process.

packer.json

  "ros_version" : "v1.1.4",

      ]
   }
 ]
}

cloud-config.yml

#cloud-config
rancher:
  ssh_authorized_keys:
    - ssh-rsa AAA ... some VALID RSA email@email.com
  network:
  interfaces:
    eth0:
      dhcp: true
    dns:
      nameservers:
        -8.8.8.8
        -8.8.4.4

Edit: Added these lines in the builder and removed their equivalents from provisioners. This still does not solve the other steps that I want to have, but at least cloud-config is uploaded and configuration can be done.

      "http_directory":"http",
      "boot_command":[
          "<esc><esc><enter><wait>",
          "wget http://{{ .HTTPIP }}:{{ .HTTPPort }}/cloud-config.yml <enter>",
          "sudo ros install -d /dev/sda -f -c cloud-config.yml -i rancher/os:{{ user `ros_version` }}",
          "<enter>"],

RancherOS doesn't have ssh password enabled by default. See issue #1467
