uname and pacman show different kernel version

cygosw · 2020-11-07 06:41:50

Hey,

I'm having issues with virtualbox, and after a lot of tinkering I noticed there is a difference between the output of the two commands, and I wonder if that is related to the problem (can't load virtualbox kernel modules):

$uname -r
5.9.2-arch1-1

$sudo pacman -Q linux linux-headers
linux 5.9.4.arch1-1
linux-headers 5.9.4.arch1-1

And when I try to update it:

$sudo pacman -Syyu

there is nothing to do

And I did reboot the system several time, so that didn't help.

Hi,
Only reboot...

The common cause is that you forgot to mount the boot partition when updating or the reverse, that you mounted a /boot partition but actually boot from the root partition.
Please
a) use code tags when posting shell I/O
b) post the outputs of "mount" and "file /boot/vmlinuz-linux"
c) assuming the /boot partition is mounted, unmount it and check whether there's a vmlinuz-linux in the unmounted /boot path - testing it w/ "file" will probably show the updated kernel?

file

$file /boot/vmlinuz-linux

So what should I do next?

Check unmounted filesystems for one containing vmlinuz-linux in its root directory then check if that kernel is version 5.9.2 using file.

Can you explain in noob's term what do I need to do?

Output of "lsblk -f"?

Mount sda1 and look at its contents.
