As you can see, there's no Packages file for AMD64
http://www.gpsdrive.de/ubuntu/dists/intrepid/main/binary-amd64/
But, amd64 debs are included in I386 Packages file
http://www.gpsdrive.de/ubuntu/dists/intrepid/main/binary-i386/Packages
This makes impossible to install anyting for AMD64.
try http://www.gpsdrive.de/ubuntu/pool/

I know that the .deb files are stored in http://www.gpsdrive.de/ubuntu/pool/ but without Packages file in /dists you cannot automatically update and Synaptic shows an ugly message.
Ok, the buildbot server and .deb repo on the website belongs to Joerg, you'll have to ping him to get it fixed. em ail to joerg TA ostertag.name
Repairing this will take a little bit, since the PC holding the buildcluster and the gpg-keys started to throw flames and smoke and then changed my working-room into a dark-room. So i had to send it to the manufacturer (today) to repair the Main Power supply. But as soon as it is back I'll have a closer look at this.
yikes!

OK; the PC is not repaired, but replaced wit a new interims PC. I tried to fix it. There was a amd64 missing in the config.
