Further to the above: 1. I found persisting references to earlier, now long-gone kernels in /var/lib/initramfs-tools, but not a complete list (there were 17, but there might have been many more if all the old kernel listings had been retained). 2. I manually deleted all but the newest and immediately prior references. 3. After confirming the system data via dpkg enquiries, I ran 'sudo dpkg --configure -a' which did not work. 4. I then ran 'sudo apt-get -f install' which allowed the new kernel extras installation to complete properly.
The cause of the installation failure was the attempt by the installer to generate multiple initrd.img- files (as instructed from /var/lib /initramfs-tools) which rapidly filled /boot leading to the software break; these redundant initrd.img- files must be deleted from /boot for the above steps to work (ie. to make space for the installer to proceed within /boot). These steps have solved this episode; it seems likely that with further time, a new set of outdated kernel data will accumulate in /var/lib /initramfs-tools, requiring manual deletion. Automating this clean-up at the time of kernel updates may be entirely inappropriate on many systems. The above may assist others. I look forward to more expert assessment.
