Hello! At the moment, I try to install Arduino on my Ubuntu 10.04 (32 Bit) computer. I downloaded the latest release at http://arduino.cc/en/Main/Software, cd'ed to the directory and unziped the package. When I try to run ./arduino , I get following error:

Exception in thread "main" java.lang.ExceptionInInitializerError
    at processing.app.Base.main(Base.java:112)
Caused by: java.awt.HeadlessException
    at sun.awt.HeadlessToolkit.getMenuShortcutKeyMask(HeadlessToolkit.java:231)
    at processing.core.PApplet.<clinit>(Unknown Source)
    ... 1 more

Here is my java -version output:

java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.5) (6b20-1.9.5-0ubuntu1~10.04.1)
OpenJDK Server VM (build 19.0-b09, mixed mode)

Any suggestions on this? I try to install arduino without the 'arduino' package.

I tried to install it with apt-get (sudo apt-get install arduino).

When I try to start arduino (using arduino command) will cause following error:

Exception in thread "main" java.lang.ExceptionInInitializerError

Update: I saw that I installed several versions of jre (sun and open). So I uninstalled the open jre.

Now, when calling arduino I get a new error:
