kdeartwork kdeartwork-theme-desktop kdebase kdeprint kept back

["Mihalis I. Tsoukalos" <mtsouk@freemail.gr>]

Dear list,

why do I get the following message:

racoon:~# apt-get upgrade
Reading Package Lists... Done
Building Dependency Tree... Done
The following packages have been kept back
  kdeartwork kdeartwork-theme-desktop kdebase kdeprint
0 packages upgraded, 0 newly installed, 0 to remove and 4  not
upgraded.
racoon:~#

I think that those packages should have been updated?

TIA,
Mihalis
