[SOLVED]failed to open encryption mapping, device ... is not LUKS vol

Hi friends,

After installing packages via pacman, I ran into this issue. I'm not exactly sure if it was a package or a pacman update that caused it(or something else)  but now I can't boot.

I get

Failed to open encryption mapping, the device UUID=... is not a LUKS volume and the crypto= parameter was not specified.

running hook [resume]
Waiting 10 seconds for device /dev/mapper/secret

...

You are being dropped into an emergency shell

My partitions are
sda1 system
sda2 swap
sda3 luks encrypted

The uuid is the correct uuid for sda3

I know the luks headers are ok because I can mount the luks partition using a live USB with the following:
cryptsetup open /dev/sda3/secret -type luks
enter passphrase...
mount /dev/mapper/secret some_dir

My symptoms seem similar to https://bbs.archlinux.org/viewtopic.php?id=209210 , but I think that author is operating at a higher level than me, if possible I would like a dumbed down solution with clear steps from either the emergency shell or a live USB.

I can't use cryptsetup in emergency shell because it requires GLIBC_2.33 required by /usr/lib/libdevmapper.so.1.02

I am using systemd-boot instead of grub2

Much appreciated!

Please post the pacman.log for the update that caused the issue onward.  ( /var/log/pacman.log )  If the file is too big to fit in code tags please see the tip box from pastebin.

[2021-02-12T13:03:08+1100] [ALPM] running 'update-desktop-database.hook'...
```

The last entry kolourpaint seems quite fishy for something that is just an image editor. (messing with mkinitcpio.conf), I remember looking that that and thinking hmm haven't seen that stuff before. I would also hate to cast doubt on their program because I have no clue what I am looking at myself.

In either case, it would be stuff from the 12th or less likely the 11th, if the issue is from pacman.

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

Failed to open encryption mapping, the device UUID=... is not a LUKS volume and the crypto= parameter was not specified.

You are being dropped into an emergency shell

I know the luks headers are ok because I can mount the luks partition using a live USB with the following:

Does it work in the emergency shell? If yes then it should be a wrong kernel parameter. Otherwise something else.

cryptsetup open /dev/sda3 secret

In the emergency shell, also check `cat /proc/cmdline` and `cat /proc/partitions` - in particular if the kernel parameters are passed as expected, and the devices themselves present.

EDIT:

I can't use cryptsetup in emergency shell because it requires GLIBC_2.33 required by /usr/lib/libdevmapper.so.1.02

Missed that bit, sorry. Does the issue persist after rebuilding initramfs from chroot?

Yeah it doesn't work in emergency shell(missing lib), see above.

Will look into other suggestions

This is the point that reaches beyond my capabilities, I would need a step by step on that one.

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

chrooting is what you use during installation of archlinux, but you can always chroot into an already installed system the same way and fix things from there

described in more detail here https://wiki.archlinux.org/index.php/chroot

from arch livecd, you can use arch-chroot, from any other livecd you can use the manual https://wiki.archlinux.org/index.php/ch … ing_chroot

you have to mount your rootfs and then chroot into it. from there you can run pacman updates, mkinitcpio, etc. as you would if you booted properly

I just updated my arch just to be sure and cryptsetup in initramfs works fine for me.

chrooting is what you use during installation of archlinux, .

Ok thanks! So what would be the exact commands for rebuilding initramfs after chroot? I am reasonably familiar with chrooting, I just don't want to make it worse for myself and I don't actually know what initramfs is, but researching now.

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

Update:
archchroot /mnt/mountpoint
mount /dev/sda1 /boot (my system partition is sda1)
mkinitcpio –p linux

Command completes fine, but still same issue upon reboot

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

From the chroot what is the output of:

pacman -Qi glibc cryptsetup

The pacman.log you posted did not contain either cryptsetup or glibc so I could not tell from it.

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

Those match,  again from inside the chroot:

pacman -Qi device-mapper

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

That is  the problem device-mapper 2.03.11-3 needs glibc 2.33-3.  Somehow the system has been partially updated.  Downgrade device-mapper and lvm2 or perform a full system update.

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

This fixed it ! Thank you so much.

Root cause was mismatched package versions between device mapper and glibc

Full process for anyone else who is struggling:

In live-usb :

1. Decrypt the partition with cryptsetup open /dev/sda3 <some name>
2. mount /dev/mapper/<some name> <some dir>
3. arch-chroot into <some dir>
4. mount /dev/sda1 /boot (if you don't do this, when linux kernal updated with pacman -Su, it cannot not save the base image for mkinitcpio in /boot), in my case, my system partition was sda1
5. pacman -Su (i had to pacman -S linux, because I forgot to mount the /boot the first time, but I am confident if boot was mount Su would work the first time)
6. mkinitcpio -p linux
7. exit chroot then reboot

Big shout out to loqs & everyone else who helped me, thanks again!

Re: [SOLVED]failed to open encryption mapping, device ... is not LUKS vol

I have the same issue but i dont have a partition type luks encrypted

On one of the computers, when loading the system, there is the same error. Although there is no luks section in the system

No, neither of you have the same problem. Don't bump old threads, open your own if you have an issue.
