[ABANDONNE] 20.04.2 Réinstall sans pertes sur partition chiffrée LVM
Bonjour,
J'ai un problème important (./viewtopic.php?id=2063027) qui, faute de solution, va sans doute m'obliger à réinstaller le système.
J'ai vu qu'on pouvait le faire sans pertes de données/paquets mais je n'ai pas l'option "réinstaller" lorsque je boote sur une clé USB.
Est-ce possible ?
Merci d'avance !

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).

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 restore-efi-backups
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 Ubuntu 20.04.2 LTS entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !Il s'agit d'une installation entièrement chiffrée. Elle a été faite avec le choix "Chiffrer la nouvelle installation de Ubuntu pour la sécurité" (j'en parle dans ce fil). Désolé mais je ne suis pas assez connaisseur de ce type d'installation pour répondre à tes questions.

Re : [ABANDONNE] 20.04.2 Réinstall sans pertes sur partition chiffrée LVM
OK, merci pour ton aide.
Quelqu'un a-t-il une idée ?
Y a-t-il une commande permettant de décrypter le disque lors du lancement d'une session live USB ?

Re : [ABANDONNE] 20.04.2 Réinstall sans pertes sur partition chiffrée LVM
Je viens de faire un essai dans une machine virtuelle dans laquelle j'ai une installation chiffrée de Ubuntu 20.04 comme la tienne.
J'obtiens ce Boot-info depuis une session live de Ubuntu 20.04, après avoir monté la partition chiffrée (il faut donner la passphrase). Ne pas tenir compte de sdb et sdc, ils ne sont pas dans la manip. Tout se passe dans sda.

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
sdc2,
using the following options: sdc1/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 Ubuntu 20.04.2 LTS entry (sdc1/efi/****/shim****.efi (**** will be updated in the final message) file) !Dans la foulée, je lance l'installateur et j'obtiens cette fenêtre à l'étape "Type d'installation" : 
Donc aucune proposition de réinstallation avec conservation des documents et fichiers personnels. Ce qui est proposé, c'est une suppression de l'installation donc une suppression de tous les docs et fichiers personnels. Il existe peut-être une procédure adaptée pour parvenir à réaliser une réinstallation "sans pertes" comme tu as mentionné dans le titre de la discussion mais moi je ne connais pas.

Re : [ABANDONNE] 20.04.2 Réinstall sans pertes sur partition chiffrée LVM
Bonjour,
J'ai fini par réinstaller tout le système. (Ce qui, malheureusement, n'a pas résolu mon problème...)
Merci pour votre aide à tous en tout cas !

Re : [ABANDONNE] 20.04.2 Réinstall sans pertes sur partition chiffrée LVM
J'ai finalement réinstallé à partir de zéro.
Il s'est avéré que mon problème de figement d'écran était lié au kernel.
