FWIW, if all you want is for the shutdown button to work, this application is completely unnecessary. The button is on the standard/default shutdown pin, GPIO 3, so all you have to do is add this to your /boot/config.txt:
# Enable shutdown button on GPIO 3
dtoverlay=gpio-shutdown
If you'd prefer to set the defaults explicitly:
# Enable shutdown button on GPIO 3
dtoverlay=gpio-shutdown,gpio_pin=3,active_low=1,gpio_pull=up,debounce=100
As a bonus, pressing the button while shut down will start the pi back up again. I think that works either way, but.
