Support Request: Installation problems with Linux

Problem: Minecraft will not load with IC2 installed

I am using IC2 v1.15 and running no other mods of any sort. I started with a fresh Jar file and followed the instructions and steps immaculately. I am attempting to help my sister who is using Ubuntu (version natty narwhal 11.04 I believe) I have it running perfectly well on my PC which runs on Windows and I have set up a server which is working just fine however I cannot seem to figure out how to help her get it working on her PC. I copied some of the command responses when I try to run it here:

destiny@Mr:~$ LIBGL_ALWAYS_INDIRECT=1 minecraft
Invalid or corrupt jarfile /home/destiny/.minecraft/minecraft.jar

If I don't delete the META-INF folder it will start to run and then freeze and this is the command prompt for that:

destiny@Mr:~$ LIBGL_ALWAYS_INDIRECT=1 minecraft
java.io.IOException: Cannot run program "javaw": java.io.IOException: error=2, No such file or directory

I would deeply appreciate any help with this as IC is our favorite pastime.

If you have Skype, I can walk you through a step by step process of how to mod minecraft correctly on Linux (I'm running Ubuntu myself, 10.10).

Don't use archive manager to modify jar files, it's doesn't work reliably.

lxxcraft · October 7, 2011 at 4:13 AM

what shall we use then?

Extract and recompress works, commandline-7z probably works, fastjar works.

I just installed ubuntu last week and i need help getting this mod to work for 1.15 i had 1.00 just fine but now every time i want to put the volume up it crashes. i used archive manager for both of them, and just for the record i am trying to mod a single payer.

details for extract and recompress would be alright with me, if that is possible

You can use archive manager to extract+recompress it, only adding files to an existing archive is broken.

Look inside your minecraft.jar for a directory called lang/java (or java/lang) and copy and paste the modloader.class file that's in there into the parent of the .jar file.

I'm not sure what the root cause of this issue is, I added a tentative fix though.
