Hello
Thanks to the fresh iso of Siduction and the wiki
https://wiki.siduction.de/index.php?title=Verschl%C3%BCsseltes_System_mit_LUKS/dm-crypt_und_LVM_aufsetzen I was able to install today Siduction with /boot no encrypt, a wide encrypted LVM containing two partitions / and /home.I have only one password to enter.
Some remarks1) With
cryptsetup -c aes-xts-plain64:sha256 -y -s 512 luksFormat /dev/sda2
, the command
cryptsetup luksOpen /dev/sda2 cryptsda2
gives an error message "Luks no recognized". So I copy/paste another crypsetup command containing some random command, and it was ok.
2) as explained by agaida : the cli-installer
3) I had also to manage uefi. Of course my first boot was a failure, due to uefi (I made nothing). Since I have a uefi partition (Dell "gives" ubuntu preinstalled with uefi), I keep the uefi partition and following the instruction
https://wiki.archlinux.fr/GRUB#Mise_en_place_2, it seems that it is ok
the laptop boots, I have to enter the passphrase and enjoy xfce appears !
The only "not really" problem is an error message before grub. On the black screen, two lineserror : no such device: 564(lot of hex-numbers)erro : disk lvmid/yI(hex-numbers/(hex numbers) not availablethen waiting or typing keyboard : grub menu, siduction boots !
And I think that the video card is not perfectly managed, presence of flashs in tty or during the passphrase sequence.
Many thanksO.G.
