Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
mapper/vgubuntu-root,
using the following options: sda2/boot, sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file
Confirmation request before suggested repair: __________________________________
You may want to retry after mounting your encrypted partitions so that the tool can verify their contents. (https://help.ubuntu.com/community/EncryptedPrivateDirectory)
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 20.04.1 LTS CurrentSession entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Je crois comprendre qu'il s'agit d'une installation propre de la version 20.04. Alors pourquoi tu nous embrouilles en écrivant : "passage de ubuntu 18.04 à 20.04" ? Quand on lit ça, on pense que tu as fait une
mise à niveau de 18.04 vers 20.04.
EDIT : je te prie de donner le retour complet (*) de cette commande :
cat /etc/default/grub
Ainsi que le retour complet (*) de cette autre commande :
cat /boot/grub/grub.cfg
(*) définition de ce qu'on appelle "retour complet" :
