Package missing: kde-i18n-de-trinity

Hello list, I am currently using TDE 3.5.12 on Debian Squeeze and want to upgrade to latest version. Although I have added the entries from ppa.quickbuild.pearsoncomputing.net (...) trinity-v.3.5.13, I cannot upgrade because some package seems to be missing. Here is the output from apt-get upgrade, it contains the URL of the package in question. root@dannytrinity# LC_ALL=en_US.utf-8 apt-get upgrade Reading package lists...

Err http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian/ squeeze/main kde-i18n-de-trinity all 4:3.5.13-0debian9+r1181027+pr1~squeeze 404 Not Found Failed to fetch http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian/p… 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? If you manually browse to the folder http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian/p… you will see that it is in fact empty, so I assume its a build problem. Please upload the new i18n package, since we want to use Trinity in the German language.
