Describe the bug

Hi there, I'm trying to get photonvision running on an arm64 debian 11 device. My current thinking is that the PATH variable is not being picked up by photonvision.jar based on the below (though welcome an alternative diagnosis):

java.io.IOException: /root/.wpilib/nativecache/linux/arm64/1cc8e0c0c9df1063c6f3789cda757535/libwpiutiljni.so could not be loaded from path

What's confusing is that if I explicitly set the path variable in a shell, prior to run to:
PATH=PATH:**/root/.wpilib/nativecache/linux/arm64/1cc8e0c0c9df1063c6f3789cda757535**/lib:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

I still get the same issue when invoking
sudo java -jar photonvision.jar

Iirc someone else saw the same error message -- maybe search through GitHub issues and discord message history to see if you can find that?

Tried installation today and receive the same result on


Description:    Ubuntu 22.04.3 LTS
Release:        22.04
Codename:       jammy

Why is the jar complaining at runtime that it's unable to find the libs in path, even after PATH contains the lib files?

Resolved.

Things I did wrong: I ran apt-get update and apt-get upgrade after install. This (oddly) broke the installation environment expectations and caused the above issues.

Actually.... This service may have just needed a PATH variable set in the systemd service config.

https://stackoverflow.com/questions/63377036/systemd-unable-to-find-java explains how to add a PATH variable at startup.
