Grub error: no such cryptodisk found

Issues & Assistance
1

Hello,

I have Garuda Linux (KDE, but I guess it doesn’t matter) installed with default LUKS encryption from the installer. I have been using this for nearly half a year, no problem at all.

But recently (2 weeks ago, maybe) I got one.
But it isn’t too critical, I guess. So far, I have mostly ignored it, it doesn’t cause any problem aside from a little annoyance.

How it behaves:
I turn on my PC, I enter my LUKS password, I wait. Then there is grub graphical menu, I select Garuda. And then I see

error: no such cryptodisk found
loading Linux linux-zen ...
loading initial ramdisk ...

Press any key to continue...

And that’s it. After pressing any key or waiting ~10s it just proceeds to boot as usual, nothing strange.

How it’s different from similar issues on this forum:

Mainly, I don’t have any problem with rebooting. I have done it, maybe, 15 times since the first appearance of this message.
So far, nothing has broken.

What I want to know:
A way to get rid of this annoying line.
And also the reason, why it has appeared.

What I think may be the reason:
I have 2 different theories about the source of the problem:

  1. Broken grub update.
    This possibility is mentioned in here and here . Yet I don’t understand enough, what should I do. I tried to uncomment GRUB_ENABLE_CRYPTODISK=y and add "cryptodisk" into the GRUB_PRELOAD_MODULES, everything in /etc/default/grub, but this does nothing for my problem. (I did run grub-mkconfig)
  2. It’s because of me breaking something while trying to set up auto-mount of second SSD (also encrypted) in my laptop, using different guides from the internet.
    Maybe, i have wrote something in fstab-like file. I don’t know, I’m too noob for this.
    Btw in the end I have set up auto-mount using gnome-disks gui.
    And no, I did it after the first occurance of my error, so this can’t be the reason.

Anyway, I will be grateful for any sort of help.

Thank you.

Hi @Marenleka, welcome to the community. :slightly_smiling_face:

The garuda-inxi output is missing from your post.

You can take a look at the UUID of your mounted volumes by running lsblk -f. Check to see if there is a UUID specified in /etc/fstab or /etc/crypttab that does not appear on the output of lsblk -f. If you are not sure, paste into the thread so we can take a look.

lsblk -f

cat /etc/fstab

cat /etc/crypttab

If there are any UUIDs listed that no longer exist (from the effort to set up auto-mount of the second SSD, perhaps), that could cause the error message you are seeing because systemd will continue to attempt a mount at every boot.

Updating Grub is not a bad instinct, but you may get a different result by reinstalling Grub first. I’m not sure if you have an EFI system or not (no garuda-inxi posted), but if so you can simply run:

sudo grub-install

Then regenerate the configuration file.

sudo update-grub

Paste the input and output into the thread if you see anything unexpected.

Honestly, I don't see anything out of order here.

Trying to run sudo grub-install leaves this output:

Installing for i386-pc platform.
grub-install: error: install device isn't specified.

And I'm too scared to write anything in options and arguments, so to not break system even more.

However, sudo update-grub generated a far more adequate output:

I guess I will reboot now and see if anything has changed

Upd. post reboot — nothing has changed. Error is still there.

It looks like you are not using EFI after all:

“Legacy” indicates the installation was done in BIOS mode, in which case you will have to reinstall Grub like so:

sudo grub-install --target=i386-pc /dev/nvme0n1

Then run sudo update-grub again.

So, doing sudo grub-install --target=i386-pc /dev/nvme0n1 left this output:

Installing for i386-pc platform.
Installation finished. No error reported.

Which seems good so far.

And the output of sudo update-grub is similar to the previous one.

So rebooting again.

UPDATE: So yeah, that really was because of some Grub breakage after some package update (I guess).
And the reinstallation of Grub really solved my problem.

Thank you very much!
