Rebooting after update causes "grub_calloc" error. Trying to restore grub on encrypted system - luks & EFI

[MaddestMax]

Hi all. I’ve been working on this for 3 days now and getting nowhere. I’ve been pointed in the direction of the wiki to the grub restore page and to this link about chroot-ing into an encrypted partition. I’ve also scoured the web and found some other things I found. I came up with a game plan and it didn’t work. Below is that plan in three sections: 1. my system structure. 2. my command attack list I cobbled together from multiple sources. And 3. my terminal session including errors. I’m sure I’m making some rookie mistake somewhere, but I can’t see it. Hopefully one of you kind souls can help me out.

[Solved] Can't boot after today's update

Hello everyone, after today’s update, I can’t boot my Thinkpad. The update notes said: You need to re-install grub on your system to complete the security fix I assumed that I was supposed to re-install grub after a reboot with the new kernel and packages. I guess I was wrong…? My Manjaro installation uses full disk encryption. After entering my passphrase, the machine attempts to decrypt for a while as usual, but then drops me into grub rescue. The error messages are: error: access deni…

also before going in chroot check
in terminal

inxi -Mxxxa
test -d /sys/firmware/efi && echo efi || echo bios
sudo parted -l 
sudo efibootmgr -v

@stephane

inxi -Mxxxa
test -d /sys/firmware/efi && echo efi || echo bios
sudo parted -l 
sudo efibootmgr -v

That was one of the things I saw before my original post. I didn’t see anything that worked for me. My password is on the standard EN keyboard that Manjaro installs with.

I input the commands you suggested before chroot. Here is the return:

Looks like mostly system info. I didn’t see anything that would change the process, unless I’m missing something. (Highly likely! ) I’ll edit this comment in 5-10 when I complete the process again. Thanks!

EDIT - as expected, nothing changed. After inputing my password, I get the same “grub_calloc” error.

boot on USB iso manjaro
open a terminal

sudo manjaro-chroot -a ( type 1 if only one line appears )
sudo cp /boot/efi/EFI/manjaro/grubx64.efi /boot/efi/EFI/boot/bootx64.efi
exit

[MaddestMax]

@stephane

First command returns:

==> ERROR: You can’t mount 0!

[stephane]

type 1 if only one line appears 

[MaddestMax]

@stephane
I’m sorry if I’m missing somthing, but no combination of typing 1 does anything.

[manjaro@manjaro ~]$ sudo manjaro-chroot -a
==> ERROR: You can’t mount 0!
[manjaro@manjaro ~]$ 1

-q Query settings and pretend

If 'command' is unspecified, manjaro-chroot will launch /bin/sh.

If 'automount' is true, manjaro-chroot will launch /bin/bash
and .

[manjaro@manjaro ~]$ sudo manjaro-chroot 1

[manjaro@manjaro ~]$

[stephane]

sudo manjaro-chroot -a 

if there is only one line 0 - …
then type 1 enter

[MaddestMax]

It doesn’t give me that option. It spits out :

==> ERROR: You can’t mount 0!

and returns immediately to the CL. No pause.

[MaddestMax]

I have a feeling this older post might have the answer to my problem. I’m not competent enough to put it together.

[stephane]

are using Luks ? ( encrypted installation ? )

[MaddestMax]

Yes, I am. I can mount through Thunar like the post suggest, but then I can’t mount the /boot.

Reinstall grub + BIOS + fully encrypted LUKS partitions, will this work?

Background My manjaro system is installed to sda1 (root (/), boot (/boot), home (/home) are all on sda1) and swap on sda2. Both sda1 and sda2 are encrypted with LUKS. And my system uses BIOS and not UEFI (sda has an msdos partition table and there isn’t any /boot/EFI directory on my system). Currently, everything works fine. I don’t want to mess something when I reinstall grub. So I want to verify in advance that I’m doing things correctly. manjaro is my main workstation. Maybe I should also…

[MaddestMax]

I don’t see anything that pertains to my situation. I’m not attempting to do the procedure from within Manjaro. I’m locked out at using a live USB. I’m also not dealing with dual booting. I only have Manjaro on my HD.

[stephane]

you have to read this
https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system

1 how to mount open luks
2 and reinstall grub

[MaddestMax]

The word “reinstall” isn’t even on that page. I feel like I’m going deeper down a rabbit hole than I need. I can mount the drive! But I can’t figure out the right order to do things in, or apparently where the files are actually supposed to go. I really appreciate your help, but I feel like I’m getting further from the solution at this point.

[stephane]

from USB iso manjaro
you can select your drive to boot ?
( not live , but the disk ? )

[MaddestMax]

I’m sorry. I don’t understand what you’re asking. I can mount my system drive from Thunar (or the CL) within the live system.

[stephane]

from USB iso manjaro ( before start booting )
you can click on boot to select your disk

is this working ?

[MaddestMax]

From the USB boot menu, I can choose to look at the EFI bootloaders. Listed as follows:

(hd1,gpt1)/efi/manjaro/grub64.efi
(hd1,gpt1)/efi/boot/bootx64.efi
(hd1,gpt1)/efi/boot/grubx64.efi
(hd1,gpt1)/efi/boot/Manjaro/grubx6464.efi
