Warning:  Ubuntu ("close enough" to Debian to confuse me, multiple years) regularly requires dist-upgrade to do their frequent Kernel Upgrades, because they change Version Numbers on, among other things, the vmlinuz file.  So, when I do "apt-get upgrade" on the remaining Ubuntu Laptop, I regularly see things like, 

>> root@EyeBlinkLenovo:~# apt-get -d upgrade
>> Reading package lists... Done
>> Building dependency tree       
>> Reading state information... Done

But then, "apt-get dist-upgrade" gets me "new packages", where only a "sub-version" is different.  For example, when the "smoke clears" from the dist-upgrade, my "vmlinuz", in my /boot directory consists of (among other things)

>> vmlinuz-4.4.0-124-generic
>> vmlinuz-4.4.0-127-generic

Note that these are different Packages.

Now I know, that Ubuntu is aimed, at a less technical audience, but this threw me for a loop (and came to the foreground, when I didn't allocate a large enough /boot partition.  I had to learn "apt-get autoremove" in a HURRY!!!  Oh well.  I;m sure each of you have your own Administration War Stories).  

But this "Feature Creep" on the Linux Kernel, is why I am here now, "upgrading" my Ubuntu Server Systems to Debian 9.4.  Once again, Go Debian!)

So, once again, watch out for "dist-upgrade", if there's any "hint" of Ubuntu (i.e.   Mint, Elementary OS, and many others out there).

Word to the Wise.
