Can't boot after kernel update (couldn't mount /efi)

General system Newbie
1

After updating to 6.4.1.arch2-1 from 6.3.7.arch1-1 and rebooting I get a error that it failed to mount /efi and to see systemctl status efi.mount for more details. After I run that command it says that it has a unknown file system vfat.
I saw somewhere that I needed to run reinstall-kernels but that command doesn’t exist for me and I can’t install it with pacman or yay.

Here’s the output of systemctl status efi.mount:

× efi.mount - /efi
     Loaded: loaded (/etc/fstab; generated)
     Active: failed (Result: exit-code) since Wed 2023-07-05 15:19:37 CEST; 7min ago

If you need any more info, let me know

That seems odd.

From a chroot can run the following command and share the output here:

 pacman -Q | grep -E "(dracut|mkinitcpio)"
3 
dracut 059-1

Is the output of that command

4

It looks like you removed kernel-install-for-dracut. You need to reinstall that package and then run reinstall-kernels.

There may be other issues as well but try that first.

5

reinstall-kernels did its thing and I rebooted but the problem persists. I also saw that in the boot menu it says 6.3.7 instead of 6.4.1 as the kernel version, might be relevant?

6

Can you do it again and share the output here before rebooting?

Here’s the output of that command

How about findmnt --real

I chrooted into /dev/sda2 from the livecd so idk if the output is correct:

TARGET
  SOURCE    FSTYPE OPTIONS
/ /dev/sda2 ext4   rw,relatime

You didn’t mount the EFI partition. Since that is where the files get written, that is probably why it didn’t fix it.

11

Should I just downgrade and try to update again?

12

No, just mount the EFI partition in the chroot and re-run reinstall-kernels

13

Where should I mount it to? mount /dev/sda1 /efi?

14

If you are inside the chroot, yes.

15

That worked tho now I have 3 kernels to choose from: LTS, 6.3.7 and 6.4.1. How can I remove the old version?

16

You need to delete the extra data in /efi/loader/entries and /efi/<machineid>

Machine ID is a long string of numbers and letters. Be sure not to delete everything in those directories. Only the files related to older kernels.

Thank you for your help!
