[Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

Bonjour à tous,
Lundi matin, sans crier gare, le DD sur lequel boote l'un de mes PC a décidé de lâcher (HP ProLiant MicroServer Gen10).
En démarrant à partir d'une clé usb live, j'ai eu un beau message disant que le disque SSD était en train de mourir.

J'ai donc changé le disque SSD et refait une belle installation toute propre sur un DD tout neuf. Partitions, formatage, tout a été fait en automatique à partir de la clé. Installation sans internet, puis maj.

Ce PC contient 3 DD
1 SSD avec le système d'exploitation Ubuntu18.04 (aucun windows installé)
2 DD mécaniques de données (NTFS)

Ce matin, mercredi, lors du redémarrage de l'ordinateur après une mise à jour, tout s'est bloqué.
Écran noir avec le message suivant :
aa_small.jpg

J'ai démonté préventivement mes disques de données et redémarré à partir de la clé live.
J'ai installé boot-repair, dont voici le rapport
http://paste.ubuntu.com/p/Sy8QBGZ3R5/

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!


=================== User settings
The settings chosen by the user will not act on the boot.

J'ai lancé la réparation, mais ça s'est mal passé :

An error occurred during the repair.

Please write on a paper the following URL:
http://paste.ubuntu.com/p/tdkdHVfpgp/
In case you still experience boot problem, indicate this URL to:
boot.repair@gmail.com 

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.efi file!

An error occurred during the repair.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/shimx64.efi file!

Dans le bios, j'ai bien trouvé le disque Kingston, mais rien de plus…

Après vérification dans le BIOS, il semble que Secure Boot soit désactivé (si j'ai bien compris).

Pas moyen de démarrer, par contre GRUB apparait au démarrage quand je passe par le choix de boot (aucune trace de sda1/EFI/ubuntu/shimx64.efi...)

Que puis-je faire maintenant ?
D'avance merci.

MAJ 16h : j'ai essayé de redémarrer avec plusieurs configuration dans le BIOS :
Avec le Secure boot, le BIOS propose plusieurs settings :
- custom (choisi à l'origine),
- standard avec key factory
- standard sans key factory
Aucune config n'a résolu le problème.


Modération : merci d'utiliser des images de petite taille (300x300) ou des miniatures pointant sur ces images (Des hébergeurs comme Toile Libre ou TDCT'Pix le permettent).

Re : [Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

Tentes les options avancées pour booter sur un ancien noyau voir si ça boot meiux ainsi.

Re : [Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

Bonsoir Lucmars,
Merci pour ton aide, mais je n'ai pas compris ce que tu veux dire.
Les options avancées de ? À l'invite de commande de l'image 1 ? En passant quelle commande ?
Dans le bios ? Grub ?

J'ai essayé à partir de GRUB, en sélectionnant : linux 4.18.0-15 generic
J'arrive sur l'écran violet d'Ubuntu, puis sur l'invite sur fond noir du début de mon 1er message.

J'en suis là.

Si c'est vraiment sans solution, je peux essayer de réinstaller Ubuntu (en perdant mes données), mais comme ça semble coincer dès le BIOS, je ne sais pas trop quoi faire.

Re : [Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

Oui, les options avancées du menu grub.

Dans le rapport on voit que t'as la 180403 : une rolling release avec upgrade des noyaux, t'as le v5 et le v4.18.

La 180401 lts s'en tient à la version 4.15 si je ne me trompe et c'est pas une rolling. Si ton Proliant n'a pas du matos récent, rabats-toi sur cette lts.

Pour la récupe des données, semble que la première capture impliquait du cryptage, t'avais choisis de crypter le disque ?

Sinon, t'as tout dans la partoche efi, que le bios soit secure boot ou non; je doute qu'il soit en cause (vaut mieux pas)

Re : [Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

Merci pour ces précisions.

Avec Grub, ça n'a rien donné, j'ai tenté avec  linux 4.18.0-15 generic, comme expliqué dans mon message précédent. (il propose aussi la 5.0.0.32 generic, je pense que c'est celle par défaut)
ça a bloqué ici :
aa5_small.jpg

Le matos a 2 ans je crois.
Je n'ai rien crypté sur cet ordinateur.

Est-ce que tenter un nouveau formatage / installation résoudrait le problème ? Comme c'était une installation toute fraiche, il n'y a quasiment pas de données sur ce PC. J'accède sans souci aux données à partir de la session Live.

Je ne sais plus quoi faire pour résoudre le souci.

D'avance merci

Re : [Résolu] Ubuntu 18.04 : Couldn't get UEFI db list, emergency mode

J'ai réussi à régler le problème en bidouillant les paramètres EFI du BIOS (Secure boot, avec ou sans les paramètres constructeur)
