I'm running a raspberry pi 4 8GB with Ubuntu 21.10 as AMP fails to install on Raspbian and it was just a pain.
So I've been trying to fix this missing jar file issue on and off for a few days now.
I thought it was because i had to have java 17 installed for it to work properly but I've spent an hour trying to figure out how to install that and its still not working so now Im stuck.
i hope im just being stupid and its an easy fix.
Thanks, Ryan
