Problems with apt-get source

[Darshaka Pathirana]

Hey!

I am having problems doing:

% apt-get source fai-quickstart
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Could not open file
/var/lib/apt/lists/www.informatik.uni-koeln.de_fai_download_dists_lenny_koeln_source_Sources
- open (2 No such file or directory)

My sources.list:

,----
| deb http://www.informatik.uni-koeln.de/fai/download lenny koeln
| deb-src http://www.informatik.uni-koeln.de/fai/download lenny koeln
`----

I then did:

% apt-get update (instead of aptitude update)

which ends with:

,----
| W: Failed to fetch http://www.informatik.uni-koeln.de/fai/download/dists/lenny/Release
| Unable to find expected entry  koeln/source/Sources in Meta-index file
| (malformed Release file?)
`----

Whats wrong? Any clues?
