sources via apt

[Philip Blundell <Philip.Blundell@pobox.com>]

I added this line to /etc/apt/sources.list, as instructed on the web page:

	deb-src ftp://ftp.ipv6.nl/pub debian/

Unfortunately, `apt-get update' now gives:

Err ftp://ftp.ipv6.nl debian/ Sources                                          
  Unable to fetch file, server said '/pub/debian/Sources.gz: No such file or directory  '

Is there something else I have to do to make APT download the sources?

Thanks

p.
