How to fix corrupted download

[Ross Boylan <RossBoylan@stanfordalumni.org>]

Is there an easy way to force apt to download a deb again?  I seem to have got a corrupted one:

(Reading database ... 131943 files and directories currently installed.)
Preparing to replace xfonts-75dpi 4.1.0-5 (using .../xfonts-75dpi_4.1.0-6_all.deb) ...
Unpacking replacement xfonts-75dpi ...
dpkg-deb: subprocess paste killed by signal (Broken pipe)
dpkg: error processing /usr/var/apt/archives/xfonts-75dpi_4.1.0-6_all.deb (--unpack):

I think it's just my download, not the version on the server, that's corrupt.

Thanks.
