I have make upgrade on my server and reboot the server to use the last kernel, but after reboot, the server just use the old kernel (4.19.0-16-amd64).

In /boot/, I just seen files for kernel 4.19.0-16-amd64. If I do apt install linux-image-amd64 the result is linux-image-amd64 is already the newest version (5.10.46-4) but this kernel version is not available in /boot/, so update-grub do nothing.

What can be wrong on my serveur ?

If I do ls -l on /, I can seen this two line:

lrwxrwxrwx   1 root root    27 Aug 18 16:22 vmlinuz -> boot/vmlinuz-5.10.0-8-amd64
lrwxrwxrwx   1 root root    28 Aug 17 13:38 vmlinuz.old -> boot/vmlinuz-4.19.0-17-amd64

But this two kernel not exist in /boot/ folder.

FYI : my server use Raid5 also for /boot/ partition.

I reply to myself after find a solution.

I do apt install --reinstall linux-image-5.10.0-8-amd64 and after that the new kernel is correctly available in /boot folder.

The command update-grub give good result.
