I recently received the new ZideLook software from the download area,                                                               
and am now trying to upgrade from our previous (2.0.2) version, which                                                               
came in a tarball named skyrix5-ogo-zidestore-20051201.tgz. Attempting                                                              
to install the sx-zidestore-ng-etch_1.5-2_all.deb results in a

Is there a documented upgrade path between editions here?
