Just a little FYI, I'll assume you are using the CDs from Ship-it.  The 
Ship-it CDs are desktop CDs.  They contain a lot of the packages in 
compressed form in the squash-fs file system.  As such, IIUC, most of 
those packages are not available as real packages to apt.  This makes 
the desktop CD quite a bit less useful as an upgrade CD for an existing 
installation.  If you really want an upgrade CD, the alternate install 
CD would be *much* better.
