Errors were encountered while processing: linux-headers-6.16.3-76061603-generic

The error "Errors were encountered while processing: linux-headers-6.16.3-76061603-generic" typically occurs because the new kernel is not compatible with certain drivers, such as those for NVIDIA, VirtualBox, or Razer devices, that use a DKMS module. To fix this, first try to reconfigure your package manager with
sudo dpkg --configure -a
and
sudo apt install -f.

If that fails, you may need to uninstall the specific package causing the conflict before installing the new kernel, then reinstall the package, or revert to the previous kernel while a fix is developed.

To fix the error

Reconfigure and fix broken packages:

Run
sudo dpkg --configure -a
to fix any broken dependencies.
Run
sudo apt install -f
to install any missing packages.

Identify and remove the conflicting package:
The error message will often point to the specific DKMS module causing the failure, such as virtualbox-dkms or amdgpu-dkms.
If the conflicting package is not immediately obvious, you can try uninstalling other drivers and modules that might be causing issues.

If you find the conflicting package (e.g., virtualbox-dkms), uninstall it with

sudo apt remove --purge <package_name>

.

Reinstall the new kernel and other packages:
After removing the conflicting package, reinstall the new kernel and attempt to configure any other related packages.

sudo apt update
sudo apt upgrade

Reinstall the removed package:
If the new kernel is installed correctly, you can try reinstalling the removed package.

sudo apt install <package_name>

If the above steps fail:

You may need to revert to the previous kernel. You can do this by selecting an older kernel from the GRUB boot menu.
Wait for an update from your distribution's repository that provides a DKMS module compatible with the new kernel.
