My Raspberry PI 4 Configuration notes

Install imager on Ubuntu

sudo apt install rpi-imager

Write Ubuntu ARM64 on Micro-SD

Automatically connect to a wireless network configuration

Replace the network-config file content in system-boot partition with this:

# This file contains a netplan-compatible configuration which cloud-init
# will apply on first-boot. Please refer to the cloud-init documentation and
# the netplan reference for full details:
#
# https://cloudinit.readthedocs.io/
# https://netplan.io/reference
#
# Some additional examples are commented out below

version: 2
ethernets:
  eth0:
    dhcp4: true
    optional: true
wifis:
  wlan0:
    dhcp4: true
    optional: true
    access-points:
      "SSID_REPLACE_ME":
        password: "PASSWORD_REPLACE_ME"

Probably on the first boot the raspberry pi will not connect to Wifi network. Infact the first boot is the configuration boot. Reboot ubuntu and it will work.
