Ubuntu 10.04 - Tekkit (mod_netherores error)

[owen_a]

Hello everyone.

I've tried running the tekkit server, however I get stopped with an error which hasn't seem to be fixed. Below you may find what happens when I launch the shell script 'launch.sh' with the following arguments...

#!/bin/sh

java -Xmx768M -Xms512M -jar Tekkit.jar nogui

 

Below is the output from the terminal...

desktop@ks3098701:~/gameservers/tekkit$ sh launch.sh
