Installing Ubuntu (and valetudo app) on my Xiaomi Vacuum cleaner gen 1

I have installed ubuntu on my old Xiaomi Vacuum cleaner gen 1 (< year 2000) using OTA update. Now it cleans and speaks Italian funny messages with the voice of my children.

I just followed the suggestions from

• official valetudo website (https://builder.dontvacuum.me/index_xiaomi.html) and
• https://www.ajfriesen.com/cloud-free-robot-vacuum/
• https://github.com/dgiese/dustcloud/tree/master/devices/xiaomi.vacuum/audio_generator (/opt/rockrobo/resources/sounds/PRT)

Before I had to hard reset it (pressing “reset button” with both buttons, after some seconds I released “reset button” and kept pressed the 2 buttons until I listened a chinese voice)
