I followed cryptsetup manual to setup LUKS encrypted root partition https://cryptsetup-team.pages.debian.net/cryptsetup/encrypted-boot.html - EFI bios - EFI partition 700Mb - LUKS encrypted partition containing both / and /boot - LUKS mapped device directly contains ext4 partition without LVM To do this I added a second disk, added EFI and root partions on it and copied all files preserving attributes and permissions. I modified files in etc and after chroot I executed: > update-grub > grub-install /dev/sdb After rebooting and disabling first disk (/dev/sda) I was immediately brought into grub shell I can notice what there is an error message flashes before booting "No such device: c740ceea-853c-487c-82ef-3d2138f9a7d7" I can also "source" (hd1,gpt1)/efi/ubuntu/grub.cfg and it will produce the same error. Also cryptodisk.mod module is not loaded. I can also add insmod ... lines into the (hd1,gpt1)/efi/ubuntu/grub.cfg but it does not help find partioon using following line: search.fs_uuid 85030321-f93d-47dc-aa4c-70bf751ad3f7 root cryptouuid/c740ceea853c487c82ef3d2138f9a7d7 If I try to type ls (hd1<TAB> it will show me following information: grub> ls (hd1) Possible partitions are: Device hd1: No known filesystem detected - Sector size 512B - Total size 10485760KiB Partition hd1,gpt1: Filesystem type fat, UUID C3AC-7168 - Partition start at 1024KiB - Total size 716800KiB Partition hd1,gpt2: No known filesystem detected - Partition start at 717824KiB - Total size 9767919.5KiB Relevant files: Mounting script I used to mount everything before chroot: cryptsetup open /dev/sdb2 root mount /dev/mapper/root root mount /dev/sdb1 root/boot/efi mount --bind /dev root/dev mount --bind /sys root/sys mount --bind /proc root/proc /etc/crypttab root UUID=c740ceea-853c-487c-82ef-3d2138f9a7d7 none luks,discard /etc/default/grub GRUB_DISABLE_OS_PROBER=true GRUB_ENABLE_CRYPTODISK=y /boot/efi/EFI/ubuntu/grub.cfg search.fs_uuid 85030321-f93d-47dc-aa4c-70bf751ad3f7 root cryptouuid/c740ceea853c487c82ef3d2138f9a7d7 set prefix=($root)'/boot/grub' configfile $prefix/grub.cfg > blkid /dev/sdb1: UUID="C3AC-7168" TYPE="vfat" PARTUUID="d50cd38a-ada3-f44a-bd39-0ea2f8355158" /dev/sdb2: UUID="c740ceea-853c-487c-82ef-3d2138f9a7d7" TYPE="crypto_LUKS" PARTUUID="e527fa37-f546-6041-b376-40d2463d0812" /dev/mapper/root: UUID="85030321-f93d-47dc-aa4c-70bf751ad3f7" TYPE="ext2" Relevant versions: Ubuntu 18.04.3 LTS cryptsetup 2:2.0.2-1ubuntu1.1 grub2-common 2.02-2ubuntu8.13 Cleanup script: umount root/dev umount root/sys umount root/proc umount root/boot/efi umount root sync Added GRUB_PRELOAD_MODULES: crypto gcry_rijndael gcry_sha256 pbkdf2 cryptodisk luks More links: - https://gitlab.com/cryptsetup/cryptsetup/wikis/LUKS-standard/on-disk-format.pdf - https://www.gnu.org/software/grub/manual/grub/html_node/Simple-configuration.html#Simple-configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1844153/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
