Merci de votre retour @Mips.
Désolé pour la log non formatée, celle ci sera mieux!
Suite au reboot et a la réinstallation du plugin la log des dépendances est différente. Visiblement je dois choisir un disque mais je n’ai pas l’invite pour le faire…
Du coup j’ai tenter une seconde installation des dépendances et la seconde log ressemble à la première communiquée 
J’ai essayé aussi de faire un refreshValue : erreur 500

Configuring grub-pc
-------------------
The GRUB boot loader was previously installed to a disk that is no longer
present, or whose unique identifier has changed for some reason. It is important
to make sure that the installed GRUB core image stays in sync with GRUB modules
and grub.cfg. Please check again to make sure that GRUB is written to the
appropriate boot devices.
If you're unsure which drive is designated as boot drive by your BIOS, it is
often a good idea to install GRUB to all of them.
Note: it is possible to install GRUB to partition boot records as well, and some
appropriate partitions are offered here. However, this forces GRUB to use the
blocklist mechanism, which makes it less reliable, and therefore is not
recommended.
