Addition to the above comment by sarnold, I tried with the 5.4 kernel, and that seemed to compile ok. But it still fails for 5.11 installed on the same system, regardless of changing $KERNELS to $CURRENT_KERNEL. Here is some relevant output:

The comment at https://askubuntu.com/questions/969352/uninstalling- and-then-reinstalling-nvidia-384-kills-colord tells us that /var/lib/dpkg/info/nvidia-340.postinst has a typo: replace $KERNELS with $CURRENT_KERNEL then `dpkg-reconfigure nvidia-340` works as expected.
