OK, I found out that the first problem is that update-notifier is 
supposed to launch from a shortcut in /etc/xdg/autostart -- the same 
location that nm-applet is supposed to launch from.  But it is well 
known that nm-applet fails to launch from that location under 14.04.  In 
fact, nothing will.  See Bug 1309698 - Lubuntu does not handle 

If one employs the same workaround as for nm-applet, manually adding 
update-notifier as an autostart app, then update-notifier appears as a 
running process.

*BUT*, I have not yet been prompted to install any updates.  I 
understand that update-notifier is supposed to poll for updates every 
180 seconds.  So whatever was at work in 
(starting with 12.04) seems to be failing here still.

Some of the Ubuntu-related servers seemed to be out of commission 
earlier today, so maybe that comes into play also.

I see that some people have gotten results with update-notifier.  I 
don't know what may be different here.  This is on a laptop, so some 
default settings may be different than for desktops.


On another point from my original post -- the difference between updates 
offered by update-manager vs. apt-get -- I found out that update-manager 
respects the Phased Updates mentioned earlier by Dale Visser, and 
apt-get (and Synaptic) do not.  They will offer everything that has been 
released.  See bapoumba's post at Software Updater not notifying 
though I don't know which of his three references he is drawing that from.


@BrendanP: update-notifier is used to issue the reboot reminder, so that 
is a related issue.
