Consider the 3 following scripts :

from gpiozero import Button

stopButton = Button (17)
while True:
if stopButton.is_pressed:
os.system ("sudo shutdown now -h")
time.sleep (1)
exit (1)

import RPi.GPIO as GPIO

from threading import Thread
GPIO.setwarnings (False)
GPIO.setmode (GPIO.BCM)
shutdown_pin = 26
GPIO.setup (shutdown_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
def shutdown_check():
while True:
pulsetime = 1
GPIO.wait_for_edge (shutdown_pin, GPIO.FALLING)
print ("falling detected")
time.sleep (0.01)
while GPIO.input (shutdown_pin) == GPIO.LOW:
time.sleep (0.01)
pulsetime += 1
if pulsetime >=2 and pulsetime <=3:
os.system ("sudo reboot")
elif pulsetime >=4 and pulsetime <=5:
os.system ("sudo shutdown now -h")
try:

exit (0)
3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#!/bin/python3
import RPi.GPIO as GPIO

GPIO.setmode (GPIO.BCM)
GPIO.setup (17, GPIO.IN, pull_up_down = GPIO.PUD_UP)
def Shutdown (channel):
print ("Shutting down...")
os.system ("echo $(date) >> shutdown.log")
time.sleep (3)

exit (0)
GPIO.add_event_detect (17, GPIO.FALLING, callback = Shutdown, bouncetime=2000)
while 1:

exit (1)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The above scripts are common shutdown scripts that can be found on the web, utilizing an NO pushbutton connected to GPIO 26 and ground (physical 37). None of the above scripts work though, since a falling edge is never detected. My setup has been tested and actually, the 1st script was working properly on Raspberry Pi OS a few weeks ago (before switching to Ubuntu). gpiozero uses rpi.gpio as the pin factory. A different pin was tested too.
