[Résolu] Impossible de démarrer Ubuntu (intel microcode)

Bonjour,

Un proche m’a demandé de dépanner son pc qui a le problème suivant. Le démarrage après Grub, plante et Ubuntu ne démarre pas. Démarrer le kernel 5.4.0.42 précédent permet de démarrer Ubuntu.

Sachant dépanné, je n’ai diagnostiqué aucune erreur, ni système, ni disque dur, je n’ai plus d’idée. J’ai tout de même réparé les paquets, réparé et réinstallé grub, mais aucun changement. Les paquets n'étaient pas altérés.

Lors du problème, pas d’erreur, pas de message, juste le tiret en haut à gauche qui clignote.

Pourriez-vous m'aider svp à identifier la cause ?

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub2 of
sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s

J'ai réparé les paquets avec ça, mais aucun paquets n'était altéré et les mises à jour sont à jour.

sudo apt update && sudo dpkg --configure -a && sudo apt install -fy && sudo apt autoclean && sudo apt autoremove --purge -y && sudo apt full-upgrade -y

J'ai réinstallé grub avec ça, mais aucun changement. Le rédémarrage à chaud fonctionne bien mais le redémarrage à froid crash parfois.

sudo os-prober
sudo update-grub
sudo grub-install /dev/sda

Re : [Résolu] Impossible de démarrer Ubuntu (intel microcode)

Résolu.
C'était le paquet intel-microcode qui posait problème et empêchait de démarrer Ubuntu. En supprimant le paquet, ça supprime aussi le kernel générique, donc j'ai préféré mettre à jour manuellement une version antérieur à ce paquet. Suivant ces commandes :

sudo apt install intel-microcode=3.20191115.1ubuntu3 # Pour Ubuntu 20.04
sudo apt-mark hold intel-microcode # Pour l'empecher de se mettre à jour

Le pc rencontrait ce bug :
