Subsonic Forum

I'm trying to install subsonic 6.1.6 on a raspberry pi 5 but I'm running into a problem with installing the Java file.

sudo apt-get install openjdk-8-jre
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package openjdk-8-jre

Many thanks.

I think Java 11 should work but I'm not sure. Otherwise, maybe try out a fork like airsonic that's been updated to more modern Java releases.
