Let’s go through the process of installing Ubuntu 20.04, Connect to WiFi, SSH into it and Install desktop (optionally) in this post.

  • We need to have an imager to create the bootable SD Card.

    Download and install the respective imager from here (MacOS, Windows, Linux)

  • Making bootable SD Card
    • Insert the SD Card to the computer/laptop
    • Open the imager, You see 3 steps like Choose OS, Choose SD Card, Write

    • Select “Choose OS” -> “Ubuntu” -> “Ubuntu 20.04 LTS (Pi 3/4)”

      Note: Make sure you are selecting the 64 bit OS for arm64 architectures

    • Choose the SD card to write
    • Click on “Write”. It will take some time to write into the SD Card
  • Connecting to Wifi
    • Remove and insert the SD again to the computer/laptop
    • Open the system-boot drive
    • Edit the network-config file with your WiFi configuration
    • Uncomment the wifis block in the file and add your WiFi credentials 
            wifis:
        wlan0:
        dhcp4: true
        optional: true
        access-points:
          "<WiFi name>":
            password: "<WiFi password>"

      Note: Include quotes if there are spaces in the name or password.

    • Save the file and Eject the SD Card from the computer/laptop.
  • Booting the Pi and SSH
    • Just insert the SD card into the Pi and connect it to the power.
    • It takes around a minute to boot the Pi with the Ubuntu you just installed
    • Find out the IP Address of the Pi
    • ssh ubuntu@<Pi's IP address> Example: ssh ubuntu@<192.168.0.5>
    • Confirm the connection by typing yes
    • ubuntu is the default password for user ubuntu
    • It will ask to change the password on the first time login
    • Login again with the changed password

  • Optional: Install desktop

    If you want the desktop then, You can install any light weight desktop of your wish. I have installed kubuntu-desktop which is fine but not great.

    • sudo apt update and sudo apt upgrade
    • sudo apt install kubuntu-desktop
    • sudo reboot to reboot the pi and start the desktop
    • Ideally, You new desktop should come up automatically. But in some cases it does not. Hence, you can run startx to start the desktop.

Boom….. That’s all. You have a RaspberryPi running Ubuntu 64 bit OS in it.
