ktorrent problem

[Steven Vollom]

Download failed.
The list of errors is attached. The recovery for this case is currently not 
implemented. If you see 404 errors, it might be useful to try fetching package 
lists (see the Sources tab) and retrying the operation.

The error was: 
APT Error. Context:
    Package download failed, 
    http://us.archive.ubuntu.com/ubuntu/pool/main/k/kde4libs/kdelibs5-
dbg_4.2.0-0ubuntu2~intrepid1_i386.deb: 404 Not Found [IP: 91.189.88.46 80]

I was having trouble applying a new torrent to the list of downloads.  Nothing 
worked, so I tried removing and reinstalling ktorrent.  the above errors 
appeared when I attempted download which failed.  I don't know what to do from 
here.
