Comment 14 for bug 549217

I'm the original reporter, and as far as I'm aware I am actually
getting security updates correctly auto installed - but I'm still not
getting any notification of new non-security updates (without manually
starting Update Manager).

I would be prepared to set aside some time for more investigation, but
I think I would need more specific instructions that "give steps
to reproduce from a fresh install", because we're talking about the
lack of something appearing in response to no input from the user
(rather than the more usual "something incorrect happening in response
to specific input").

Finally, I don't even really know what is *supposed* to happen when
updates arrive, as I have never seen it working in its current form
(my previous Ubuntu version was Intrepid) - all I know is that I've
ticked a checkbox and it doesn't seem to be doing what it says it
will! :)
