dist-upgrade not working...

["Eric Bass" <ebass@surfsouth.com>]

I don't know if I screwed something up or what, but the apt-get dist-upgrade
isn't working.

I believe I'm currently on 2.0 (still shows 2.0 on the login screen) Is
there a better way of
Checking your current dist?  Wanting to upgrade to slink, or possible
potatoe...
Run apt-get update, then apt-get -f dist-upgrade and I get:

Updating package status cache...done
Checking system integrity...ok
The following packages have been kept back
  slay gzip at man-db libpng2 tetex-base manpages mh xlib6 metamail

What is going on??
