Problème: Grub est configuré pour utiliser le nouveau noyau, mais démarre toujours dans l'ancien noyau

J'ai construit un nouveau noyau (4.4.0-64, sur Ubuntu 16.04).

Maintenant, je veux toujours démarrer à partir du noyau 4.4.0-64, mais peu importe ce que j'ai défini dans /etc/default/grub de GRUB_DEFAULT sur - le système d'exploitation démarre toujours avec l'ancien noyau.

L’exemple ci-dessous montre que même si j’ai défini le GRUB_DEFAULT comme étant le noyau 4.4.0-64, le système d’exploitation s’initialise toujours dans l’ancien noyau 4.4.0-040400:

$ Sudo grub-mkconfig | grep menuentry | grep generic

Je ne suis pas un expert en la matière, mais j'ai trouvé des informations similaires que vous pourriez utiliser pour résoudre votre problème.

1) courir dans le terminal: grep submenu /boot/grub/grub.cfg

2) trouvez vos noyaux dans la liste et faites attention à leur commande. La commande commence à "0". Donc, le premier noyau de la liste est "0", le second est "1" etc.

3) puis exécutez Sudo gedit /etc/default/grub et accédez à la ligne: GRUB_DEFAULT= et en utilisant les informations de l'étape 2, entrez GRUB_DEFAULT=0 (pour le noyau 0 dans la liste) ou GRUB_DEFAULT=1 (pour le noyau 1 dans la liste) etc (ou quel que soit le numéro d’ordre du noyau que vous voulez, selon le résultat de grep submenu /boot/grub/grub.cfg).

4) Sudo update-grub

5) redémarrer.

Cela a-t-il résolu votre problème?

Une solution de contournement consiste à supprimer le noyau qui chevauche la dernière mise à jour du noyau.

Pour lister les noyaux disponibles:

dpkg-query -l | awk '/linux-image-*/ {print $2}'

Pour supprimer un noyau:

Sudo apt-get --purge remove linux-[replace reference]

Dans le cas spécifique:

Sudo apt-get --purge remove linux-image-4.4.0-040400-generic

Après la mise à jour du grub

Sudo update-grub

Votre GRUB_DEFAULT me semble étrange. Quand je veux démarrer dans un ancien noyau, j'utilise un GRUB_DEFAULT comme celui-ci

GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 4.4.0-64-generic"
