Software updater installed latest kernel 4.4.0-130, I then rebooted but was unable to find it in the grub advanced settings menu. I looked for it, and determined it was not running:
dpkg -l | grep linux-image

uname -r
4.4.0-128-generic
I then ran Grub Customizer, where the new kernel was listed, saved the new config and rebooted again. The new kernel is still not running. I then opened terminal and ran:
sudo update-grub
I rebooted again with the same result.
Update: -128 and -130 appear to boot but hang just before desktop interface as though cascade failures each previous kernel is having boot issues now. Currently running 4.4.0-124
How should I proceed to troubleshoot and make the new kernel run as it normally would after this kind of update? Can I purge -130 and then re-install the update via apt? What is a safe way to do that?

I rebooted 10 times with same SOLVED RESULT also tested previous kernels back to -124, observed zero (hard boot) hangs just prior to desktop interface. Apparently this solved my problems user535733, if you restate your thoughts as a posted answer I would be happy to provide you the credit. I will study this more for future reference and edification.
The first clear problem is that you don't have the latest kernel installed: Your latest is -130 while Ubuntu is currently distributing -136. The most common reason for this kind of problem is that your
linux-image-genericmetapackage is out-of-date.Solution: Use
sudo apt install --reinstall linux-image-genericto refresh the metapackage which will, in turn, pull in the latest kernel for your release of Ubuntu.You seem to have had another, more vague second problem with several symptoms:
linux-image-genericmetapackageThere are several possible causes for these symptoms together:
/or/boot: Check withdfdf -iDisk space and apt problems usually don't clear up on their own. It seems likely that you did something --whether you know it or not-- to resolve the problem.
