The only thing I can add here (and hopefully I'm not repeating anyone here) is /boot claims to be about 75% full, and I have also seen it 100% on another system of mine. It appears the problem is during the transition between kernel 4.3 and 4.4. I use an encrypted partition on both systems, one of which is a Surface Pro 3 using secure boot (if that matters to anyone). I have only had one case where the system was unable to boot because of this. Lucky for me I have a cloud backup. The others I caught it in time. I was able to keep the system stable by fixing what appeared to be a dependency error. Then again not rebooting might have also helped. My guess is the Ubuntu installer didn't leave much space on /boot, though normally all that is stored there is a few kernels and related files. Everything appears fine now.

This is resulting in package installation failures for initramfs-tools. For example: Setting up initramfs-tools (0.98.8ubuntu3) ... update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-2.6.38-8-generic gzip: stdout: No space left on device E: mkinitramfs failure cpio 141 gzip 1 update-initramfs: failed for /boot/initrd.img-2.6.38-8-generic dpkg: error processing initramfs-tools (--configure): subprocess installed post-installation script returned error exit status 1 WORKAROUND: Remove unused kernels using computer janitor (not in repositories for 14.04 or later) or manually free space on your partition containing the /boot file system.
