Lors de l'installation de Xubuntu sur mon HP 17-bs006nf a partir d'une USBLive je recois le message d'erreur suivant :
"Echec de l'installation de GRUB
Le paquet grub-efi-amd64-signed n'a pas pu être installé dans /target/.
...."
Après moults recherches en vérifiant mon BIOS qui est bien EFI/UEFI et mes partitions avec GParted (/dev/sda1 = EFI System Partition - fat32 - Mount point = /target/boot/efi et /dev/sda2 en ext4 - mount point=/target)
En ayant essayé un boot-repair mais au lancement des lignes de commande pour effacer GRUB l'effacement n'a pas lieu donc abort de la réparation.
J'ai aussi essayé de réinstaller de force GRUB via CHOOT : rien n'y fait.
Donc là j'ai besoin de vous
Grand merci pour votre aide.Voici le bootlog :

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub-efi of
sda2,
using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Blockers in case of suggested repair: __________________________________________
/target detected. Please close the Ubuntu installer, then retry.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.3 LTS entry (sda1/efi/****/grub****.efi (**** will be updated in the final message) file) !
