Erreur lors de la mise à jour du noyau

J'essaie de mettre à jour le noyau :

La taille du noyau a-t-elle beaucoup augmenté entre 3.13.0-24 et 3.13.0-27 ? J'ai eu des problèmes en essayant d'installer la mise à jour automatique. J'ai deux noyaux installés :

• linux-image-3.13.0.24-generic
• linux-image-3.13-0-24-lowlatency
