Bug#1037105: dkms unable to compile r8168-dkms to backported kernel

[e...@null.net]

Package: r8168-dkms

Version: 8.048.03-3

I installed SpiralLinux, which installs the current Debian stable at the time the image was released, in this case, bullseye and it also enables Backports by default. During the upgrade process after the initial installation, dkms reported it was having issues with the r8168-dkms package, presumably compiling/adding (?) it to the kernel, which is a backported kernel.

The kernel version is 6.1.0-0.deb11.7-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.20-2~bpo11+1 (2023-04-23) x86_64 GNU/Linux

My network card has the Realtek r8169 chip on it, so this package was unnecessary. Once I purged the package and rebooted, network connectivity was restored. 

Although I do not require this package, I felt that it should be reported to Debian as a bug, in hopes that a fix is found for those who require the package.

Below is information that was displayed during the time dkms was having the issue, plus the log file from the stated filename.
