Unturned BattlEye Initialization Fix for Linux Dedicated Server

Unturned BattlEye Initialization Fix for Linux Dedicated Server

Running an Unturned dedicated server on Linux often results in the dreaded Failed to initialize BattlEye error in the console. This prevents players from joining any server that has anti-cheat enabled. This issue is usually caused by missing dependencies or incorrect file permissions in the BattlEye directory. This guide covers the 2026 repair process.

๐Ÿ›ก๏ธ The .so Library

The Linux version of BattlEye requires the BEServer_x64.so file to be in a specific subdirectory. SteamCMD sometimes fails to download this file correctly.

๐Ÿ”‘ Execution Permissions

Even if the file is present, Linux security policies may block the server from executing the BattlEye binary if it doesn't have the +x flag.

How to Fix BattlEye Initialization

1. Verify the Directory Structure

Ensure that the BattlEye files are in the correct location relative to your Unturned_Headless.x86_64 binary. The path should look like this:

/Servers/Supercraft/BattlEye/
โ”œโ”€โ”€ BEServer_x64.so
โ”œโ”€โ”€ BEServer.cfg
โ””โ”€โ”€ BattlEye.lic

2. Fix Permissions (The chmod Solution)

Most BattlEye failures on Linux are due to the server not having permission to "Run" the anti-cheat module. From your server's root directory, run:

chmod +x ./Unturned_Headless.x86_64
chmod +x ./BattlEye/BEServer_x64.so

3. Install Missing x64 Dependencies

BattlEye is a 64-bit binary that relies on specific system libraries not always found in minimal VPS environments. Ensure your Linux host has the following:

sudo apt-get install libssl-dev:i386 libtbb2:i386 # For older versions
sudo apt-get install libssl-dev libtbb2 # For modern 2026 servers

Pro Tip: If you are hosting on Supercraft, our automated installer detects your OS version and injects the correct BattlEye libraries into your instance folder automatically.

Disabling BattlEye (Not Recommended)

If you are running a private LAN server and cannot resolve the issue, you can disable the anti-cheat in your Config.json by setting "BattlEye_Secure": false. Note that this will make your server invisible to players using the "BattlEye Only" filter in the browser.
