Noyau à moitié installé, impossible d'installer / de désinstaller quoi que ce soit

Question

Eh bien, j'ai ce problème dont je ne suis pas sûr de la façon dont j'ai obtenu, mais j'ai besoin d'aide.

Tout d’abord, mon ordinateur exécute la version 14.04.3 LTS d’Ubuntu et le noyau actuel (celui que j’obtiens de uname -r) est 3.13.0-63-generic. S'il vous plaît dites-moi si vous avez besoin de savoir autre chose.

Mon problème est le suivant: chaque fois que j'essaie d'installer/de désinstaller un paquet, que ce soit avec apt-get ou Synaptic, j'obtiens une erreur à propos de ces paquets:

linux-image-3.13.0-65-generic
linux-image-3.13.0-65-lowlatency
linux-image-extra-3.13.0-65-generic

La sortie (par exemple, lorsque je lance Sudo apt-get install 'package-name') est la suivante:

J'ai essayé des solutions en ligne mais, jusqu'à présent, aucune n'a résolu mon problème. Certains d’entre eux (et les résultats respectifs) sont les suivants:

Si vous avez besoin d'autres informations, je serai ravi de vous les communiquer.

Si quelqu'un pouvait m'aider, cela signifierait tout pour moi. J'ai vraiment besoin de pouvoir installer/désinstaller des paquets sur ma machine, je dois donc résoudre ce problème le plus rapidement possible.

PS: n'oubliez pas que je ne suis pas un expert Ubuntu/Linux.

Cette ligne dans les messages d'erreur

/usr/sbin/grub-mkconfig: 37: /etc/default/grub: Syntax error: EOF in backquote substitution

dit, vous avez une erreur à la ligne 37, mais vous n'avez pas de ligne 37. Par conséquent, l'explication la plus probable est que vous avez une erreur de citation. Et maintenant, jetez un oeil à cette ligne, tirée de votre question:

GRUB_CMDLINE_LINUX_DEFAULT =""quiet splash intel_pstate = désactiver i915.lvds_downclock = 1 drm.vblankoffdelay = 1 i915.semaphores = 1 i915_enable_rc6 = 1 i915_enable_fbc = 1"

Vous avez trois guillemets doubles dans cette ligne. Supprimer une double citation:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable i915.lvds_downclock=1 drm.vblankoffdelay=1 i915.semaphores=1 i915_enable_rc6=1 i915_enable_fbc=1"

et n'oubliez pas le

Sudo update-grub

après avoir édité le fichier.

LittleByBlue · Answer

Il y a une erreur dans votre /etc/default/grub.

La ligne

GRUB_CMDLINE_LINUX_DEFAULT=""quiet splash intel_pstate=disable i915.lvds_downclock=1 drm.vblankoffdelay=1 i915.semaphores=1 i915_enable_rc6=1 i915_enable_fbc=1"

doit être

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable i915.lvds_downclock=1 drm.vblankoffdelay=1 i915.semaphores=1 i915_enable_rc6=1 i915_enable_fbc=1"

comme le premier produirait une erreur sémantique.
