How to install safe shutdown script for Nespi 2 case?

[rsn8887]

Is there a new way that works to install the safe shutdown scripts for Retroflag Nespi 2 case?

The instructions on Retroflag’s webpage don’t work anymore, the command just hangs forever in the shell trying to download something. This is the command I tried:
wget -O - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/install.sh" | sudo bash

From here:

Install @cyperghost's shutdown script, it's better than RetrFlag's script anyway - https://github.com/crcerror/ES-generic-shutdown.
