[SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

I've read a lot of previous issue about that, but didn't found any solutions.

I've checked that uname -r and /proc/version is not matched with the kernel version that i've installed indeed uname -r and also /proc/version gives me 

 linux-6.2.10

instead of 6.2.11 .

I've also checked that /boot is mounted at the time of 

 pacman -Syu

indeed 

 cat /proc/mounts | grep boot

returns that /dev/sda1 is mounted in /boot as expected

When i downgrade to 6.2.10 version arch returns to boot, but i don't know how to do in order to upgrade kernel without breaking boot.

Down here i leave configuration of fstab: 

 # /dev/sda2
UUID=978f1226-b3c1-4d86-8f0d-39d99fe25782	/         	ext4      	rw,relatime	0 1

# /dev/sda1
UUID=23B5-766D      	/boot     	vfat      	rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro	0 2

# /dev/sda3

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

Virtually every single thread about this (and there are many) has a solution. It's almost always an issue with a /boot partition or a bootloader. What have you tried from your searches?

I'm trying to figure out why pacman is not upgrading the kernel as expected. I won't reinstall kernel in live-iso chroot. I'm trying to do that with pacman.

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

OK, so you edited a whole lot of info into your post as I was replying.

If you unmount /boot, so you see the old kernel there? Is there a different grub.cfg there?

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

if i unmount /boot, these are the file that i found:

drwxr-xr-x  2 root root     4096 Apr 17 03:22 .
drwxr-xr-x 17 root root     4096 Apr 17 02:38 ..
-rw-r--r--  1 root root        0 Apr 17 01:22 BOOT_IS_NOT_MOUNTED
-rw-------  1 root root 72329000 Apr 17 01:59 initramfs-linux-fallback.img
-rw-------  1 root root 16392991 Apr 17 01:58 initramfs-linux.img
-rw-r--r--  1 root root 12512192 Apr 17 00:27 vmlinuz-linux

with no grub folder at all.

And the vmlinuz-linux link at the right version, with 

 file vmlinuz-linux

i obtain:

 /boot/vmlinuz-linux: Linux kernel x86 boot executable bzImage, version 6.2.11-arch1-1 (linux@archlinux) #1 SMP PREEMPT_DYNAMIC Thu, 13 Apr 2023 16:59:24 +0000, RO-rootFS, swap_dev 0XB, Normal VGA

Even if it that file should not be there, if i'm right

Excuse my wants to fix with pacman, but it's the only way to figure out how to do future kernel updates without breaking everything (and reinstall with live version)

SOLUTION:

(CHECK THAT YOUR CONFIG IS SIMILAR TO MINE BEFORE FOLLOWING MY STEPS)

  • 0. umount /boot

  • 1. removed every file exept BOOT_IS_NOT_MOUNTED (Windows' EFI is on another partition, so was not afraid of this) from unmounted /boot

  • 1.1in order to do that i've done from super user 

    chattr -i /boot
cd /boot
rm vmlinuz-linux *.img 
chattr +i /boot

    (i'll repeat myself, doublecheck before doing this command)

  • 2. I've searched also in other location of / with: 

     sudo find / -name 'vmlinuz*'

    to find if there were other installation somewhere in order to clean the one not in /boot. (i found no other entries)

  • 2. remounted /dev/sda1 to /boot

  • 3. reinstalled last kernel (even if the one on unmounted boot was the right version of kernel... idk why my system is booting from that file, and after that why it was the wrong version anyway).

  • 4. update grub

  • 5. reboot and it works

I suggest to other people with my problem to remove entry CAREFULLY, double checking that boot is not mounted,  otherwise you are going to break Arch boot and all other boot

I apologize for posting an already much discussed topic, but in any case I hadn't found a solution with that of the others

cat /proc/cmdline

But you obviously updated the kerne w/o the /boot partition being mounted at some point.

It was at the right point, and the /proc/cmdline give me always the older version
I don't understand where the version 6.1.10 binary was taken from.

EDIT: In any case, aside from this oddity I wonder how all this could have happened, "simply" using pacman with a system booted correctly, and /boot correctly mounted

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

You're booting from the /boot partition but on Apr 17, 01:58 you updated the kernel w/o the boot partition mounted - for whatever reason, but that happened.

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

The individual case aside, usually some youtube tutorial will be at the other end of that question; resulting in a "bad" fstab (there's no requirement to mount /boot otherwise) and general confusion.
The first update then typically "breaks" the system.

@madella, did you maybe try to update the kernel from the chroot on Apr 17, 01:58 and at that point forgot to mount the /boot partition?
Are there any errors in the pacman log for the update that (originally) "broke" the system?
You could also inspect teh system journal for that boot to see what might have happened to the /boot partition.

All we know is that the kernel and initramfs didn't go onto the /boot partition but at some point falsely onto the root partition.

I've never update kernel from chroot

I'll do

Re: [SOLVED] Failed to mount /boot after update to linux-6.2.11.arch1-1

Another thing we see is that people forget to mount their boot partition while setting things up, then mount it later not realizing that it's far too late and things were already set up there.

Maybe yes, but not in this case, i've been using arch for at least a year, and the system never done that before. So i do not think that is something badly set
