14.04 seems subject to bug 1046563 with update-manager/notifier

[John Hupp]

I don't find the issue in the Lubuntu or Ubuntu 14.04 Release Notes, but 
it seems like 14.04 is subject to 
https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1046563, 
reported for 12.04, in which automatic updating fails.

I was noticing that I wasn't being prompted to install software 
updates.  I ran Software Updater (update-manager) manually once and got 
a big batch of updates.  I ran it manually again today and it identified 
another batch that I could get.  It included updates for Software 
Updater, so perhaps that will fix the problem.

There is a big discussion of the problem at 
http://ubuntuforums.org/showthread.php?t=2222325. And beyond the 
notification problem, a number of people report seeing big differences 
between the updates identified by update-manager and Synaptic.
