Java 11 is required for Minecraft 1.17


When I started my 1.16.4 PaperMC-server in MineOS today it gave me this in the logs below.
Will MineOS be updated to atleast Java 11? Right now it’s 1.8

EDIT - I Might have come at this problem the wrong way, can I update Java myself? I am running latest Unraid distro with Hexparrot’s MineOS Docker.


I am also having this issue. I have seen several posts on the Turnkey forums on how to update java, however since I am a novice Linux user I am afraid I’ll break something.

Just started using Paper Server 1.16.4 on MineOS and noticed the same message on boot in the console. It would be great if someone knew whether MineOS Turnkey ISO, currently available today for download will still function with Java 11 installed.

I’ll be messing around with this in the meanwhile starting with a simple Debian O/S Java Runtime upgrade.

Wish me luck. Took me almost a day to learn about permissions to shoe horn a Forge Minecraft server into a Paper on MineOS. I really need to learn best practices for server administration and fast :slight_smile:

I found a way to update java to 15.0, this is the website that I used (it was such a pain to find)

I followed the “For Debian 9 / Debian 8:” section. I’m using a VM of mineos so your luck may vary I hope that I was able to assist.

One note on that website where it said “sudo apt install oracle-java11-set-default” that didn’t work for me but I found that “apt install oracle-java15-set-default” was a valid command so that’s what I’m using

Good luck, Void

I am using MineOS Turnkey. I was able to install Java 15 however, I was unable to make the server run. It simply won’t start. Not sure what I am missing. I’ve had to set it back to using Java 8 for the time being. I don’t fancy going down the Windows route of running my server when 1.17 comes out.
