Right, a quick how to, as Il Lombardia will be starting soon
Open a Terminal and SSH into the pi
Type
sudo apt update
 (let it complete)
sudo apt full-upgrade
(let it complete)
follow any instructions.
then
sudo reboot
SSH in again
type
sudo crontab -e
append this line to the bottom of the file
@reboot sleep 25 && sudo /usr/local/bin/restart.sh
Save and exit with ctrl + x, followed by y when prompted to save, and then enter
then make this file
type
sudo nano /usr/local/bin/restart.sh
enter text
#!/bin/bash
sudo /etc/init.d/logitechmediaserver restart
Save and exit with ctrl + x, followed by y when prompted to save, and then enter
make the file executable
sudo chmod a+x /usr/local/bin/restart.sh
  (or chmod +x)
Â
Reboot with
sudo reboot
Shut down the pi
Wait for at least one hour (longer if possible)
Boot up the pi, at around 35 secs the time on the Touch should revert to the time you shut down the pi, it should return to the current time at about 55 secs.
The Touch is now available
Time might be shorter on a rpi4 (I used a rpi3B+)
More tomorrow, hope it works for you
