Here is the point: Today, I wanted to play on a server that was requesting Forge, so I went here, downloaded the recomended build which is: 3.3.8-152

I am using Ubuntu 10.04 so I opened up the archive with forge and the minecraft.jar, copied from forge to minecraft.jar and deleted META-INF.

 

But when I start Minecraft, Surprise! Black screen! So I open it from the console and I get a crash report! Here is it:

This is anything I get! No other log files or stuff like that!

 

This error report is done with a CLEAN version of Minecraft 1.2.5! No mods, no ANYTHING! CLEAN! Why does it happen? I tried with multiple other recommended releases but same thing happened!

Please help!

The zip program you used did not copy the folders, you need to make sure to copy them all.

 

I use Ubuntu as well, I know Ark works, but I normally just use the unzip/zip commands on the terminal with a script to do it all for me.

let me give it a try!

 

Edit:

My God! It worked! I just installed Ark, extracted forge and copied over minecraft.jar and Puff! In works :D:D Thank you!

 

P.S.: You deserve a +

Heh, yeah, I bet you were using the normal gnome zip program, it kind of sucks. 

I switched to ark, supports more, more capable, it has a few odd bits, but it works.
