problème à la (re)installation d'Eclipse sous Ubuntu

Bonjour,

suite à des problèmes avec des plugins Eclipse, j'ai voulu désinstaller celui ci puis le reinstaller pour repartir sur une version propre.

Cependant une fois reinstaller je n'arrive plus à le lancer.
J'obtiens une erreur me disant d'aller voir dans le fichier de log.

Merci d'avance à celui qui pourra me débloquer ;)
