[Résolu] 18.04 Chiffrer la nouvelle install de Ubuntu pour la sécurité

Il s'agit de la proposition qui est faite à l'étape "Type d'installation" comme on peut voir sur cette vue (case à cocher*)   
Enfin les développeurs ont décidé d'améliorer cette fonctionnalité pour Ubuntu 18.04 et je pense qu'il y a du mieux même si je déconseille aux novices d'adopter ce chiffrement parce que c'est une source d'emmerdes à long terme. Les développeurs ont œuvré pour tenter de résoudre le Bug #1047384 qui existe depuis la sortie de Ubuntu 12.10 en 2012. Plus de 5 ans pour analyser le problème et tenter une amélioration, c'est bien long. Ce qu'ils ont fait pour la 18.04 : ils ont modifié le séquencement de Ubiquity - l'installateur de Ubuntu - afin que le choix du clavier soit fait avant le choix de la passphrase (la clé de sécurité). On peut voir ça dans le commentaire #48 du rapport de bug : "Moved keyboard step as early as possible". Faire plus concis comme commentaire, c'est dur. On va voir ce que ça donne en image :   
1525848671.png1525848705.png1525848738.png1525848783.png1525848862.png1525848896.png1525848928.png1525848969.png
Sur la troisième vue (Disposition du clavier), c'était "Français-Français (variante obsolète)" qui était présélectionné par défaut. J'ai dû sélectionner "Français-Français (azerty)" pour que tout se passe bien. Avec le choix par défaut, j'étais en qwerty à l'étape ultérieure "Qui êtes vous ?" de l'installation et plus grave, ma passphrase avait été prise en qwerty...

Moyennant cette sélection de "Français-Français (azerty)", la procédure d'installation se passe bien et va à son terme sans pb. Et surtout, au redémarrage de l'ordi je peux rentrer ma passphrase (ma clé de sécurité) comme je l'ai rentrée (sans devoir la traduire en qwerty) et rentrer aussi mon mot de passe sans souci à la connexion de session.

(*) à noter : quand on coche la case "Chiffrer la nouvelle installation de Ubuntu pour la sécurité", la case "Utiliser LVM pour la nouvelle installation de Ubuntu" se retrouve cochée automatiquement. C'est normal parce que ce type de chiffrement implique l'utilisation de LVM.

En complément de mon post #1, je colle ci-dessous un rapport Boot-Info réalisé depuis une session live de Ubuntu 18.04 :

=================== Suggested repair
The default repair of the Boot-Repair utility would not act on the MBR.
Additional repair would be performed:  repair-filesystems


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

Cela peut servir à identifier une install de 18.04 réalisée avec ce type de chiffrement. La présence de la mention crypto_LUKS en constitue le signe le plus évident.

Re : [Résolu] 18.04 Chiffrer la nouvelle install de Ubuntu pour la sécurité

Après la sortie de Ubuntu 19.04, je fais l'essai pour voir comment ça marche. ATTENTION : dans les posts précédents, il s'agissait d'une installation réalisée en mode UEFI alors qu'il s'agit ici d'une installation en mode Bios (non-UEFI). C'est pour ça qu'il n'y a pas de partition EFI...
Voici ce que j'obtiens après installation (boot-info réalisé depuis une session live pour voir "l'allure") :

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options:        sda1/boot,
Additional repair would be performed: unhide-bootmenu-10s


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


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

Pas de commentaire particulier à faire : ça marche comme prévu.
