Since this summer, sarge went in to stable, and etch became testing.
I have had tired to finde a dansih mirror that supporten etch, and has all the packaged on the sever.

Look here: ftp://ftp.sunsite.dk/mirrors/debian/dists/

As of yesterday, etch was added, with all packages.
The funny thing is, that is you look here:
http://www.debian.org/international/Danish/packages

The ftp list is not updated :-) and testing is still sarge :-)
The source list, is in the hole news.

here is my source.list
