Doesn’t seem to make a difference…
Output of update-grub is still the same.

Maybe reinstall grub?

42

if youre not properly chrooted you cant reinstall it…
found another way, lets try it, type exit, close terminal, open terminal:

cryptsetup -v luksOpen /dev/nvme0n1p2 cryptDrive
mount /dev/mapper/cryptDrive /mnt
mount /dev/nvme0n1p1 /mnt/boot/efi
manjaro-chroot /mnt

and post output of these commands…

43

i have no idea if thats a proper command, didn find anything when i searched for:
cryptsetup luksOpen /dev decrypt

44

Thank you tried that and re-ran update-grub, same issue - it can’t find drive for /dev/sda1

45

the grub command is good, the error is for the usb, you can ignore it… so lets try to reinstall the grub:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck 

grub-mkconfig -o /boot/grub/grub.cfg

any errors from the first command post here

46

Thanks again, no errors reported.

47

so try again installing the 5.17 kernel:
sudo mhwd-kernel -i linux517
post the output here

48

I was actually proactive and rebooted right away and it worked! Everything is back to normal it seems.

I just installed an LTS Kernel version in addition to the one already there being 5.15. I’ll also install 5.17 from the GUI now.

Thanks again so much for all your help Brahma. Any idea what might have cause all this? Broken update process perhaps?

49

yes it was probably an interrupted update…
now that you are back in your system provide output from:
mhwd-kernel -li
sudo update-grub - run this command after you finished installing kernels

50

I guess it’s cryptsetup open /dev/drive some_name

51

here it is:

Currently running: 5.15.44-1-rt46-MANJARO (linux515)
The following kernels are installed in your system:
   * linux515
   * linux517
   * linux515-rt
52

ok so uninstall the 5.15rt and also the 5.17 since its going to be end of life kernel… you can install the 5.10 LTS as a backup kernel…
post outputs from these, because you have some remnats from 5.11 kernel:
ls /etc/mkinitcpio.d/*.preset
sudo ls /boot/initramfs-*
sudo ls /boot/vmlinuz-*
sudo ls /usr/lib/modules/*

53

Here you go:

❯ ls /etc/mkinitcpio.d/*.preset
/etc/mkinitcpio.d/linux510.preset     /etc/mkinitcpio.d/linux515-rt.preset
/etc/mkinitcpio.d/linux511-rt.preset  /etc/mkinitcpio.d/linux518-rt.preset

54

you have there remnants of the 5.11
output from:
pacman -Qs linux511-rt

55

it doesn’t seem to return anything…

56

ok, so remove those remnants:
sudo rm /etc/mkinitcpio.d/linux511-rt.preset
sudo rm /boot/initramfs-5.11-rt-x86_64.img
sudo rm /boot/initramfs-5.11-rt-x86_64-fallback.img
sudo rm /boot/vmlinuz-5.11-rt-x86_64
then run:
sudo update-grub
sudo mkinitcpio -P
reboot
