package upgrade

[jack]

I added the medibuntu to my sources, and found this update this morning
for k3b.
apt-cache policy k3b
k3b:
  Installed: 1.0-0ubuntu2
  Candidate: 1.0-0ubuntu2+medibuntu1
  Version table:
     1.0-0ubuntu2+medibuntu1 0
        500 http://medibuntu.sos-sts.com feisty/free Packages
 *** 1.0-0ubuntu2 0
        500 http://us.archive.ubuntu.com feisty/main Packages
        100 /var/lib/dpkg/status

(I'm unsure what the _***_ means)

apt-show-versions k3b
k3b/feisty upgradeable from 1.0-0ubuntu2 to 1.0-0ubuntu2+medibuntu1

(I don't see any version differences here, either.)

Can someone enlighten me ?  I'm looking through the packages for kubuntu
and medibuntu trying to determine what (if any) differences there may
be.

Thanks.
