Requirements for Hass.io

After creating hass.io image, booting the PI 3B 32GB SD Card with adequate power supply and no peripherals (headless no mouse, no keyboard, no screen)

Port 8123 is responsive but only says:

# Preparing Hass.io (with logo)
(this can take up to 20 minutes)

This has been going on for over 12 hours.

So perhaps I misunderstood or did not find the requirements. I did search the install doc but it is unclear whether I need KVM (I thought I would boot, let it prepare, install the ssh or samba add-on and update the config).

Are any of the following required?

  • Keyboard
  • Mouse
  • Screen

My only apparent option is to remove power and try a forced reboot.
Any suggestions?
