Hello,
I've been playing Tekkit on my Tekkit server, mining down to lava and searching for tin, etc. All of a sudden Tekkit started freezing. I quit the Tekkit launcher and got back on the server, same problem. I stopped the server and restarted, it wouldn't start. Then I rebooted the actual computer, tried starting Tekkit, and got a java error. I googled a little bit and found suggestions to delete the mod_NetherOre.java file, so I did. The server started successfully, but all my creations (my hut) was gone.
Basically, I resorted to reinstalling Tekkit. After unziping the 3.1.2 version and doing ./start.sh, I get the following errors:
I'm not sure what to do. I did apt-get update, apt-get upgrade, apt-get dist-update. That didn't work. I also have the vanilla MineCraft server installed, and that works fine.
Edit: I am running everything under sudo, so permissions shouldn't be a problem.
Edit 2: Tried pokeybit's config folder here, unfortunately it did not work.
