Hello,
I received my Arduino Uno. I am using Debian 9 stable and not able to use the arduino soft because of this error :
jre@Debian:~$ sudo arduino
[sudo] Mot de passe de jre :
Exception in thread "main" java.lang.ExceptionInInitializerError

I already tried to follow some instructions but it doesn't help me:
1 : Looks like the IDE did not get installed properly. Install from the "Download" tab above. Before you do that, be sure to rename any existing "Arduino15" directory: /home/(username)/.arduino15 (a.k.a. ~/.arduino15)
Thank you for your help.
