In step 3, you will have issue if you use Windows 10 machine instead of Linux machine. You cannot read the file system to edit "network-config" file. To resolve the issue - boot your Raspberry Pi, log in using default user ID and password (ubuntu/ubuntu). Change the default password after changing the the config.

Edit the following file using 'nano'.

sudo nano /etc/netplan/50-cloud-init.yaml

Add WiFi details in the yaml file, save and restart. Make sure to remove '()'.


network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2

           dhcp4: true
           optional: true
           access-points:
