OK, new to linux yada yada yada...please be gentle

Either through synaptic or apt-get (does not matter) there seems to be a dependency problem with the kdelibs. I am trying to install arson which requires a few. I also tried to insall k3b and ran into the same problem. I installed k3b last week without issue. Onto the problem....the dependency tree is looking for the following:

http://security.ubuntu.com/ubuntu/po...ntu3.1_all.deb

the package out there is ...ubuntu3.2_all.deb. Same problem for kdelib4 and kdelib-bin. So, is there an explicit way to update the package dependencies (which I probably have done)? Where is this dependency tree info stored? I can't force it to a package that synaptic doesn't know exists. I'm sure there is probably something very simple i'm not doing.

THanks,

Mak.
