Autoinstall crashing - error means nothing to me.

[Jerry Geis]

Hi All,

I have tried several attempts to user-data file for autoinstall.
This is the latest - this is the error:

/var/crash/1610566874.641513586.ui.crash


my user-data file is:
#cloud-config
autoinstall:
  version: 1
  early-commands:
    - systemctl stop ssh # otherwise packer tries to connect and exceed max
attempts
  network:
    network:
      version: 2
      ethernets:
        eth0:
          dhcp4: yes
          dhcp-identifier: mac
  apt:
    preserve_sources_list: false
    primary:
      - arches: [amd64]
        uri: "http://archive.ubuntu.com/ubuntu/"
  ssh:
    install-server: yes
    allow-pw: no
  identity:
    hostname: ubuntu-00
    password: changed
    username: changed
  packages:
  user-data:
    disable_root: false
  late-commands:
  storage:
    layout:
      name: direct


I got this file off the net - because my files were ALSO crashing.
AT this point I just desire a working autoinstall file that doesnt crash.
Then I can tweak.

Anyone can share their user-data file that works ??? Thanks,

Jerry
