tanks for the answer,

the pakage ttf-mscorefonts-installer exist, it sems to be installed,
anyway the answer on the the terminal is :

E: Impossible d'obtenir le verrou /var/lib/dpkg/lock - open (11: Ressource
temporairement non disponible)
E: Impossible de verrouiller le répertoire d'administration
(/var/lib/dpkg/). Il est possible qu'un autre processus l'utilise.

with synaptic everything is blocked, because the system want's to execute
all the installations or desinstallation

you have programed. And I can't install or desinstall the pakages with
java,

the same events occurs  with the terminal as you can see and the
restauration possibility at the loading system.
 this is the action wanted by the system

gsfonts-x11 (version 0.21) sera mis à niveau vers la version 0.21
sun-java6-bin (version 6.21dlj-0ubuntu1~maverick1~ppa1) sera mis à niveau
vers la version 6.21dlj-0ubuntu1~maverick1~ppa1
sun-java6-jre (version 6.21dlj-0ubuntu1~maverick1~ppa1) sera mis à niveau
vers la version 6.21dlj-0ubuntu1~maverick1~ppa1
sun-java6-plugin (version 6.21dlj-0ubuntu1~maverick1~ppa1) sera mis à
niveau vers la version 6.21dlj-0ubuntu1~maverick1~ppa1

this is the response

E:
