Bonjour,

J’ai reçu mon Arduino aujourd’hui et j’ai installé le paquet `arduino` et `arduino-core`.  
Par contre lorsque je lance le logiciel `arduino` j’ai un message d’erreur Java.

Une idée ?

```nohighlight
jre@Debian:~$ sudo arduino
[sudo] Mot de passe de jre : 
Exception in thread "main" java.lang.ExceptionInInitializerError

Résolu. J’ai désinstallé l’IDE Arduino installé depuis les dépôts Debian et j’ai installé le paquet que j’ai récupéré directement sur le site officiel.
