I decided to get a tinypilot kvm device for testing purposes – it’s actually pretty neat. Sure I could have saved a few bucks by building it myself, but this way I save time and support someone else’s great ideas.
Anyway, to update the device, SSH to it (DNS name is generally tinypilot)
Login with tinypilot/flyingsopi
Run
/opt/tinypilot/scripts/upgrade && sudo reboot
