Hello All,

I started getting this kernel build error yesterday on the Stable branch. Not sure how to get around it. Any insight much appreciated.

Thanks Much,

Thanks for the link strombrg. Looks like Nvidia is aware of the issue at least. At this point I'll just wait and keep reading the boards. My system's not broken in any way, just can't do the kernel upgrade. I can wait for
Debian does not include the headers when the kernel upgrades
Make sure linux-headers-6.1.0-18-amd64 and linux-headers-6.1.0-18-common are installed - see screenshot from Synaptic Package Manager

Also run from the terminal
sudo dpkg --configure -a
Thanks for the reply GatorsFan,

I used Synaptic (see below) and see that the selections match the ones in the image you provided above and were already selected as installed. I also ran the command sudo dpkg --configure -a but got the same results as in my above posts. Then again, I may be missing something.

In case its not installed ... if the user installs the package: linux-headers-amd64, the correct version headers for each new kernel version will be installed along with the installation of that kernel. So, with that package installed, upgrading a kernel will install the headers for it.

EUREKA! Thanks everyone for your suggestions, especially GatorsFan. I added the backports repository and successfully installed
6.5.0-0.deb12.4-amd64. Apt upgrade was still hanging and trying to configure though so I used:

apt-get --force-yes remove 6.1.0-18-amd6

Voila! No more hanging and erroring out and now I have:

uname -r

Thanks again!!!
Good outcome, @userzero :)

If you don't already have it installed, now would be a good time to install Timeshift and take a snapshot.

Better is to take one before you do kernel changes, and then one after you are satisfied they work satisfactorily.

If/or when you are happy with the outcome, you can mark this as solved, from your first post.
