Cannot boot with current kernel
I cannot boot Linux with the current 5.10 kernel even though it is available on my system.
Code:
# dpkg-query -S vmlinuz
linux-image-5.10.0-9-amd64: /boot/vmlinuz-5.10.0-9-amd64
linux-image-4.9.0-12-amd64: /boot/vmlinuz-4.9.0-12-amd64
#
# uname -r
4.9.0-12-amd64
#
If I try to install kernel 5.10, I get the following warning:
Code:
# apt install linux-image-5.10.0-9-amd64
You are running a kernel (version 4.9.0-12-amd64) and attempting to remove the same version. This can make the system unbootable as it will remove /boot/vmlinuz-4.9.0-12-amd64 and all modules under the directory /lib/modules/4.9.0-12-amd64. This can only be fixed with a copy of the kernel image and the corresponding modules. It is highly recommended to abort the kernel removal unless you are prepared to fix the system after removal.
Abort kernel removal?
Usually, when I upgrade with apt update && apt upgrade, I get regular kernel updates and I automatically reboot to the newest kernel without getting such a warning.
Does anyone know why I am getting this warning?

You are currently booted to the 4.9 kernel.
Can you reboot to the 5.10 kernel then do the update?
If not then how about doing a reinstall of the 5.10 kernel packages so it can repair whatever failed that prevents booting to the newer kernel.

Thanks computersavvy. I cannot boot into kernel 5.10 because this option does not appear in my grub.cfg file and I would like to avoid reinstalling the whole system if possible.

Thanks colorpurple21859. I have already run update-grub to no avail.
I have just found something very strange on my system. I am running Debian Bullseye after having upgraded from Buster, itself upgraded from Stretch.
Code:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
However, when I boot and enter the GRUB menu (version 2.04), the only option I get is
Code:
Debian GNU/Linux 9 (stretch)
I am starting to wonder if I haven't made a mess with GRUB as I have both GRUB and GRUB2 packages installed:
Code:
$ aptitude search grub | grep ^i
i A grub-common - GRand Unified Bootloader (common files)
i A grub-pc - GRand Unified Bootloader, version 2 (PC/BIOS version)
i A grub-pc-bin - GRand Unified Bootloader, version 2 (PC/BIOS modules)
i grub2 - GRand Unified Bootloader, version 2 (dummy package)
i A grub2-common - GRand Unified Bootloader (common files for version 2)
$
Should I remove one of them and which one?

I have just set GRUB_DEFAULT to 0 and rerun update-grub although I wonder what this is going to change regarding my problem.

You didn't mention anything about dual booting debian and ubuntu, such details are needed to properly diagnose the problem. If the problem isn't fixed, you're most likely booting debian from ubuntu grub bootloader. Run from ubuntu.
If running update-grub from ubuntu doesn't fix the problem, post the contents of ubuntu /boot/grub/grub.cfg and /etc/default/grub.

Thanks colorpurple21859. I cannot boot Ubuntu from the GRUB menu. I get the following error message if I try:
Code:
error: no such device: 3278bcbd-etc...
error: file `/boot/vmlinuz-4.15-0-99-generic' not found.
error: you need to load the kernel first.
Press any key to continue...
I think "device 3278bcbd-etc..." refers to the ID of a particular hard drive. Over the years, I replaced my hard disk drive with a solid state drive. I did so by copying the whole old drive to the new one with the command dd. By doing so, I must have copied the identity of the old drive onto the grub.cfg file of the new drive. Therefore, I must now be booting with a wrong ID for my new drive.
