[SOLVED] How to install 1.7.2 Server? o.O

Well this is odd. First time I'm having troubles installing forge server on my debian machine.

What I've tried so far:

1. java -jar forge-1.7.2-10.12.0.1033-installer.jar --installServer

2. This downloads the minecraft server, but returns 403 for a lot of libs (e.g.: java.io.IOException: Server returned HTTP response code: 403 for URL: https://libraries.minecraft.net/net/minecraft/launchwrapper/1.9/launchwrapper-1.9.jar. pack.xz)

3. Ends with error: These libraries failed to download, try again. org.scala-lang:scala-compiler:2.10.2

4. Installing Server under Windows then uploading libraries etc., then starting with "java -jar forge-1.7.2-10.12.0.1033-installer.jar" starts the server, but when loading the world results in java.lang.NoClassDefFoundError: net/minecraft/client/multiplayer/WorldClient

5. Starting the server with "java -jar minecraft_server.1.7.2.jar" always results in the vanilla server only to be started, no errors.

6. Couldn't find any up-to-date manual on installing the server on linux

Ok, the 403 Error seems to have disappeared, the NoClassDefFoundError was because I accidently copied Optifine over.

Let's see if i can fix my mod crashes...
