Install Witty Pi 3 software on Ubuntu

Origin Author: Carlos Aguado (caaguado AT xcentra DOT com)

Witty Pi 3’s software is officially tested under Raspbian (Raspberry Pi OS) only. However if you would like to run it on Ubuntu (like I do), you can get the information you need here.
Raspbian (Raspberry Pi OS) and Ubuntu are different Linux distributions, but they are both based on Debian, so the difference is not that huge. With reasonable effort you can have Witty Pi 3’s software installed and run on Ubuntu. Here are the steps that need to be done:

Confirm that 1-Wire Interface is disabled:

Reference: https://www.raspberrypi-spy.co.uk/2018/02/enable-1-wire-interface-raspberry-pi/

cat /boot/firmware/config.txt|grep -in dtoverlay              ## This should show nothing.
ll /sys/bus/w1/devices/              ## This should fail with "No such file or directory".

1 2	cat /boot/firmware/config.txt\|grep -in dtoverlay ## This should show nothing. ll /sys/bus/w1/devices/ ## This should fail with "No such file or directory".

Backup Ubuntu’s original important boot configuration files:

ll /boot/firmware/config.txt /boot/firmware/cmdline.txt
ll /home/ubuntu/__boot__firmware__config.txt_*.ori /home/ubuntu/__boot__firmware__cmdline.txt_*.ori /home/ubuntu/__boot__firmware__config.txt_*.latest /home/ubuntu/__boot__firmware__cmdline.txt_*.latest
yes|sudo cp -v /boot/firmware/config.txt /home/ubuntu/__boot__firmware__config.txt_`date +"%Y%m%d_%H%M%S"`.ori

Check the original contents of the two main boot configuration files:

cat /boot/firmware/config.txt
cat /boot/firmware/cmdline.txt

1 2	cat /boot/firmware/config.txt cat /boot/firmware/cmdline.txt

Reboot and Check if Everything is OK

## Reboot now to see if the Raspberry Pi boots up properly:
date +"Rebooting system `hostname` at %Y-%m-%d %H:%M:%S %Z" && sudo reboot
## Reconnect to the Raspberry Pi and run:
sudo pwd ## Just to force password input!

ll /usr/local/bin/wittypi/*.log
cat /usr/local/bin/wittypi/wittyPi.log
