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

Software Updater appeared again today. That's two days in a row. I left
some updates uninstalled, so if it appears again tomorrow I am ready to
call this solved.
For anyone just tuning in now, the bug in which 14.04 does not autostart
anything from /etc/xdg/autostart affects update-notifier (yes, it's in
the Release Notes, but I only remembered the application to nm-applet).
But the behavior of update-notifier and update-manager is governed by
software-properties-gtk (Preferences: Software & Updates: Updates tab),
and the setting there to "Automatically check for updates: Daily" seems
to be not a statement about how often update servers are checked, but
rather how often updates will be offered to the user. So even after I
got update-notifier running via the prescribed workaround, my testing
method (rebooting after changing this, that or the other, then waiting
to see if Software Updater would appear) was doomed to show that updates
were unreliable. If the user refuses updates once for the sake of
testing, and reboots another 100 times that day, the updates will not be
