update available or not?

[D. R. Evans]

More update weirdness... (Why is it that update issues seem to consume
so much reflector bandwidth? Or is it just me imagining it?)

So...

0. Using dapper.
1. I am running amarok 1.4.3.
2. Adept Notifier tells me that there are three updates available [is
there some way to discover from which apt source it thinks they are
available??]
3. The three packages to be updated are all amarok related
4. For example, current amarok package is: 2.1.4.3-0ubuntu8~dapper1
and the candidate updtae package is: 2.1.4.4-0kubuntu2
5. Open synaptic to perform the update
6. Execute "Mark all upgrades"
7.The status bar of synaptic says: 18509 packages listed, 1416
installed, 0 broken, 0 to install/upgrade. 0 to remove
8. If I select "amarok" and check its properties, synaptic says that
it's installed and upgradeable.

What's going on? Can anyone please explain in plain English?
