Bug#216394: netinstall on sparc fails, due to dpkg being corrupt?!?

[Mike Hughes <me@mikehughes.net>]

Package: dpkg
Version: 9.1.21_sparc

Hello, im trying to do a net install of debian (woody) on my ss20, but
when it gets to installing the base system, it fails saying 

http://ftp.debian.org:80/debian/pool/main/d/dpkg_1.9.21_sparc.deb was
corrupt

upon selectign continue, it takes me back to the option screen, with the
top option being Install base, ive tried with several sites, including

http.us.debian.org
ftp.debian.org
www.mirror.ac.uk
ftp.br.debian.org
ftp.au.debian.org
ftp.uk.debian.org

but still no luck :-/

regards,
Mike.
