Boot error: Failed to start D-Bus System Message Bus

Support
21

I followed this guide, i.e.

  1. Open the crypted boot volume
  2. Mount it to some helper folder (e.g. /chroot)
  3. Mount the efi partition inside (/chroot/boot/efi)
  4. Add the additional mounts described, i.e.
mount --bind /proc /chroot/proc
mount --bind /dev /chroot/dev
mount --bind /sys /chroot/sys
  1. Chroot with `chroot /chroot’

Then I try to fix grub following this guide, shared by @soundofthunder:

  1. Instead of chroot /chroot' I use manjaro-chroot /chroot /bin/bash`
  2. Re-install grub with
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck
  1. Then create the config with:
grub-mkconfig -o /boot/grub/grub.cfg

I end up at boot with message:

ERROR: device 'UUID=3e5e...'  not found. Skipping fsck

mount: /new_root: can't find UUID=3ef5....
ERROR: Failed to mount UUID=3ef5... 
You are no being dropped to emergency shell.
...

I use

cryptsetup -v luksOpen /dev/<dev> <mapper_name>

for opening the luks.

For completeness, I also share my crypttab and fstab:

# /etc/crypttab: mappings for encrypted partitions.
#
# Each mapped device will be created in /dev/mapper, so your /etc/fstab
# should use the /dev/mapper/<name> paths for encrypted devices.
#
# See crypttab(5) for the supported syntax.
#
# NOTE: You need not list your root (/) partition here, but it must be set up
#       beforehand by the initramfs (/etc/mkinitcpio.conf). The same applies
#       to encrypted swap, which should be set up with mkinitcpio-openswap
#       for resume support.
