RuntimeError: Failed to add edge detection
</pre>
The reason is caused by the '''rpi.gpio''' library not being upgraded after the kernel upgrade, which can be referred to here https://github.com/raspberrypi/linux/issues/6037 to know more detailand solutions
The solution is as follows:
replace '''rpi.gpio''' with '''rpi-lgpio''' by running sudo apt update && sudo apt install python3-rpi-lgpio the following command: --auto-remove --purgesudo apt update && sudo apt install python3-rpi-lgpio --auto-remove --purge
