supprimer chiffrement global avant mise à jour version

Vertsaxo

Bonjour,
je voudrais passer à la nouvelle version LTS d'Ubuntu, je suis pour le moment sur la version LTS précédente, 18.4.
j'avais installé avec chiffrement et par précaution j'aurai voulu supprimer le chiffrement avant de faire la mise à jour

et je n'ai aucune idée comment procéder, je ne trouve rien qui m'éclaire.

cordialement

Bonsoir.
Tu es en version 18.04 encore maintenue 3 ans. Continue de faire sa mise â jour. Tout ira bien.

Dans deux ans, tu pourras installer la 22.04 â coté. Tu en profiteras pour ne pas chiffrer le logiciel
.
Si tu ne veux plus chiffrer tes données, fabrique une nouvelle partition et fais les transferts des répertoires de données.

Bonjour et merci géole pour cette réponse

en fait je voulais mettre à jour pour deux raisons :
mon épouse va acheter un portable sur lequel je voudrais la convaincre d'installer ubuntu plutôt que windows et j'aurai voulu lui montrer le dernier système en date
- cela fait des mois que j'ai un dysfonctionnement avec Ubuntu 18.4 : je suis obligé de passer par le bios à chaque démarrage sinon il ne démarre pas. en activant un réparateur, il me signale le chiffrement et me demande si je veux postposer la réparation pour d'abord désactiver le chiffrement donc je me dis que cela fait sens.

Bonjour
Tu peux toujours faire un boot-info. Quelquefois on voit des anomalies.
Cela serait bien que tu donnes le nom du "réparateur " et la phrase exacte de son conseil.
Si tu évoques boot-repair/boot-info , afin d'accéder à la partition, il doit te demander de monter la partition à sa place car il ne connaît pas la phrase d'ouverture pour lire le contenu. Mais cela ne doit pas être une raison pour ne pas chiffrer si tu as trouvé que cela était nécessaire.

Bonjour,
il s'agissait bien de boot-repair
voici le message :
"Vous souhaiterez peut-être réessayer après avoir déchiffré vos partitions. (http://doc.ubuntu-fr.org/ecryptfs)
Voulez-vous continuer ?"

je voulais déchiffrer avant de réparer puis rechiffrer après...

voici le lien vers mes info de boot :

Bonjour
Effectivement le message est aussi visible dans boot-info

=================== Advice in case of suggested repair
Vous souhaiterez peut-être réessayer après avoir déchiffré vos partitions. (http://doc.ubuntu-fr.org/ecryptfs)
Voulez-vous continuer ?

Je vais tenter de demander à l'auteur de voir s'il ne serait pas possible de changer la traduction. Je pense à une phrase de ce style

=================== Advice in case of suggested repair
Vous souhaiterez peut-être réessayer après avoir monté vos partitions chiffrées  afin que l'outil puisse examiner leur contenu. ([url]http://doc.ubuntu-fr.org/ecryptfs[/url]
Voulez-vous continuer ?)

En fait, comme c'est chiffré, il est impossible de voir le contenu de certaines zones et surtout boot-repair n'a pas la possibilité de modifier certains fichiers. Je pense notamment au fichier /etc/fstab qui doit souvent être rectifié.

Pour le boot-info, on a souvent besoin de voir le contenu de /etc/fstab lorsque le boot dure plus de 1 minutes 30 secondes afin de s'assurer qu'il n'est pas prévu le montage de partitions inexistantes ou un mauvais montage de partitions existantes.

Donc soit rassuré.
Cependant, il me semble souvent inutile de chiffrer le logiciel mais seulement les données personnelles. Cela donne le risque de retrouver des données personnelles totalement visibles dans le fichier de swap pour des experts ainsi que dans les plantages de l'O.S. communiqués aux experts ou certains extraits d'O.S. donc une sécurité au rabais probablement à 99,9999999% donc acceptable pour pas mal de personnes

a@a:~$

Une suggestion: Libère 15 Go (30 Go c'est mieux) d'espace disque et installe ubuntu 20.04 en dual boot de façon standard à coté , puis tu installeras ecryptfs pour accéder aux données avec un montage automatique et des liens pour y accéder automatiquement. Cela te permettra d'avoir une partition de données chiffrées indépendante qui récupérera un peu de place lorsque tu élimineras le logiciel de la version 18.04

Bonjour,

=================== 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/ubuntu--vg-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


=================== Advice in case of suggested repair
Vous souhaiterez peut-Ãªtre rÃ©essayer aprÃ¨s avoir dÃ©chiffrÃ© vos partitions. (http://doc.ubuntu-fr.org/ecryptfs)
Voulez-vous continuerÂ ?


=================== Final advice in case of suggested repair
N'oubliez pas de rÃ©gler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efiÂ !


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

Passe la commande suivante dans un terminal :

cat /etc/fstab

Pour moi, le résultat de la commande "cat /etc/fstab " est correct. Moi je ne sais pas comment supprimer le chiffrement de l'installation. Je ne sais même pas si c'est possible...

Vertsaxo

J'ai sauvegardé mes données sur une clé, puis j'ai exécuté bootrepair en passant outre l'avertissement sur la nécessité de déchiffrer préalablement, cela ne corrige pas le problème de boot noir.
C'est peut-être un problème sans solution à mon niveau de compréhension en tout cas.

voici le lien vers l'URL lié à la réparation : http://paste.ubuntu.com/p/285x2hj96p/

je suppose que je peux toujours prendre le risque de passer à 20.04 maintenant que je me suis protégé du risque de perte de données (?)

Vertsaxo a écrit - cela fait des mois que j'ai un dysfonctionnement avec Ubuntu 18.4 : je suis obligé de passer par le bios à chaque démarrage sinon il ne démarre pas.a

Peux-tu indiquer la référence commerciale de ton ordinateur si c'est un portable?
Peux-tu détailler la manipulation bios que tu fais?
Si ton ordinateur est un HP, il faut souvent faire une manipulation du bios.

Vertsaxo

Bonjour Géole,
c'est un ordinateur assemblé avec un processeur intel et une carte Asus
carte mère : B85-PLUS
Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz

je ne fais aucune manipulation du Bios, simplement ce que j'ai remarqué c'est que si je laisse l'ordinateur démarrer par lui-même, il se bloque sur un écran noir, alors que si j'appuie sur la touche Suppr pour entrer dans le bios puis que je clique "démarrer" il démarre ensuite normalement en me demandant la clé de décryptage, ce qui est normal.

Par ailleurs, après avoir lancé boot-repair, le message final me dit de "ne pas oublier de régler le BIOS pour qu'il amorce sur le fichier sda1/EFI/ubuntu/shimx64.efi " je ne sais pas si cela a qlq chose à voir, puisque que cela boot. Les indications de démarrage ne sont pas formulées avec un chemin.

Bonjour
Je ne sais pas donner d'idées sur le problème rencontré. Il serait bon que tu fasses un boot-info (Une nouvelle version est sortie).
Pour un peu, je penserais à un mauvais arrêt.
Peux-tu donner ce retour

sudo journalctl -b-1 | tail -50

Pour le second problème, boot-repair a bien renseigné la nvram tel qu'on peut le voir
efibootmgr -v

(debug) reinstall grub2 place-in-MBR no-BIOS_boot (mapper/ubuntu--vg-root)

=============================== Suggested repair ===============================

The default repair of the Boot-Repair utility would purge (in order to fix packages) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options:        sda2/boot,
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s      restore-efi-backups


===================== Blockers in case of suggested repair ======================

GPT dÃ©tectÃ©. Veuillez crÃ©er une partition BIOS-Boot (>1MB, systÃ¨me de fichiers non formatÃ©, drapeau bios_grub). Cela peut Ãªtre rÃ©alisÃ© via des outils tels que Gparted. Puis rÃ©essayez.
Alternativement, vous pouvez rÃ©essayer aprÃ¨s avoir activÃ© l'option [Partition /boot/efi sÃ©parÃ©eÂ :].

===================== Advice in case of suggested repair ======================

Vous souhaiterez peut-Ãªtre rÃ©essayer aprÃ¨s avoir dÃ©chiffrÃ© vos partitions. (http://doc.ubuntu-fr.org/ecryptfs)
Voulez-vous continuerÂ ?

=================== Final advice in case of suggested repair ===================

N'oubliez pas de rÃ©gler votre BIOS pour qu'il amorce sur le disque sda (ATA Samsung SSD 860)Â !

================================= User settings ================================

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

Bonjour
J'extrais cela du rapport boot-info

sda1: __________________________________________________________________________
    File system:       vfat
    Boot sector type:  FAT32
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        
sda2: __________________________________________________________________________

Je suis un peu surpris de ne pas y trouver des fichiers de boot.
Pour en avoir la certitude, peux-tu exécuter et poster le retour de ces commandes

sudo umount  -v   /dev/sda1
sudo mount   -v  /dev/sda1   /mnt
ls -ls  /mnt
ls -ls /mnt/EFI
ls  -ls /mnt/EFI/ubuntu
