Suspected Makefile error in linux-firmware 1.157.19 causes attempt to generate initramfs for absent Kernels 4.8.0-56 and 4.8.0

Asked by B. C. Schmerker

With LinUX Images/-Extras 4.15.0-22-generic, 4.13.0-43-generic, 4.8.0-58-generic, 4.8.0-56-generic, and 4.4.0-127-generic installed, sudo dpkg-reconfigure linux-firmware returns the following to Console:

With 4.8.0-56-generic present, dpkg-reconfigure shouldn't attempt to generate InitRamFS for a 4.8.0-56 (no suffix) or 4.8.0 (no build) for linux-firmware. What gives that could cause the false update-initramfs triggers?

In progress, to be titled "linux-firmware 1.157.19 attempts to generate /boot/initrd.img-4.8.0-56, /boot/initrd.ing-4.8.0 when no corresponding vmlinuz present."

SOLVED, would have been a potential bug against apt and/or dpkg, which failed to clean up after Kernel package removal. Since dist-upgraded to ubuntu Focal.
