One of the objectives of the Mancoosi project is to resolve some of the problems that users of Free and Open Source Software distributions experience when trying to install, remove, or upgrade packages installed on their machines. The specific goal of Workpackage 5 is to to build a data base of problem reports generated from such user requests to a meta-installer, which then will be used by the Mancoosi project, and the research community in general, to develop better algorithms to compute upgrade paths.
