• Terminal software:

  • PuttyAlternatively, Tio can also be used.

Live USB settings

• After live USB boots

• Run sudo subiquity

  • NOTE: On newer Ubuntu versions the installer might run automatically, so you can skip this step.

• If you see a “waiting for cloud init” message, wait until it times out and opens the installer (could take some time since some services should finish starting in the background).

• Proceed with your preferred installation settings and await completion

• Wait until installation is complete

• When prompted, remove the installation media and press enter

• Device will be rebooted

    the usbcore.autosuspend=-1argument is used to enable all 4 of the usb ports.

  • save the file and run: update-grub
