[ SOLVED ] Kernel version is different from uname and pacman

Hello,

I just did a full system upgrade on my archlinux (uefi + dualboot with win10)

And i have an issue, the kernel version from

uname -r
Linux archlinux 4.16.13-2-ARCH

is different than

pacman -Qi linux
Nom    : Linux
Version: 4.17.2-1

My /boot is well set in the fstab and was mount during the full system upgrade (pacman -Syu)

fstab
UUID=XXXXXXXXXXXXXXXX       /boot      ext4      rw,relatime,data=ordered    0 2

ls -l /boot
efi (empty)
initramfs-fallback.img
initramfs-linux.img
initramfs-linux-its-fallback.img
initramfs-linux-its.img
vmlinuz-linux
vmlinuz-linux-lts

( i have tried to intsall the lts kernel too pacman -S linux-lts)

Do you have any idea? Maybe it's related to the UEFI?

Kind regards,

C

Re: [ SOLVED ] Kernel version is different from uname and pacman

Probably your boot partition was not mounted when you did the upgrade of the kernel.  Mount the boot partition on /boot and reinstall the linux package.  Fix your /etc/fstab to ensure it is mounted for future updates.  Unmount the boot partition and look in /boot; there are probably a kernel file and and initrd file in there that do not belong.  Unless you are not using a boot partition, the /boot directory, when not used as a mount point, should be empty.  Updating the kernel with nothing mounted on /boot causes the flies to appear.

Edit: I was posting whilst you were editing.  Are you sure it was mounted?  unmount it and look in /boot;  see if it is empty.
Edit 2:  Another possibility; the UEFI from which you are booting is not what you think it is; perhaps you are mounting the wrong volume?

Why is /boot ext4 on a UEFI booting system?

Oh! Nice catch.  Kind of meshes with my second edit.

/boot can be anything you want, as long as the ESP is fat, for example mounted as /boot/efi.

EDIT: grep some mkinitcpio out of /var/log/pacman.log and see if the image has been built. Try rebuilding it (wiki:mkinitcpio) and see what happens.

You were right
