Unable to access Jarfile

[hexparrot]

@Boots

local: unable to open mineos.log

My guess is you’re somehow requesting to find /var/log/mineos.log on your local machine, and not on your remote server (MineOS).

@Boots

When I run that, the only thing that ever shows up is “Unable to access jarfile minecraft_server.1.15.2.jar”

When you run it how?

@Boots

I have read that using a name that doesn’t follow the minecraft_server. . .* format can cause issues.

This is not the case. Any server file can be called literally anything, so that’s nothing to worry about.

@Boots

Looking around it seems that I have to update Java.

This is exactly the issue, indeed. It corresponds to:

@Boots

Unsupported major.minor version 52.0

You do need to upgrade your Java to 1.8 for 1.15.2.

The system doesn’t recognize sudo or apt

When you’re running into issues, providing the input and the output is the only way for us to help troubleshoot.

I assume you’re running MineOS Turnkey because you labelled the thread with it, so the easiest thing to do is:

1. log in as root on your server terminal. This makes sudo no longer necessary.
2. apt-get definitely, 100% should work when you’re running as root.

I don’t know how old your installation is, though. Because MineOS Turnkey based on Debian “Stretch” already has Java 1.8. If this is a new install, you shouldn’t have downloaded Jessie (which has Java 1.7). If this is a new install, start over by downloading the new ISO.

If you don’t feel like using a new ISO, follow instructions like here:

How to install Java 8 on Debian Jessie

@Boots

I unpacked a Java 8 tar.gz but the system still says it has Java 1.7.0_95.

That’s because Linux follows an order to find the first available Java path. Right now, Java 1.7 exists in system paths and wherever you extracted Java 8 is not preceding it in order
