My advice: do not proceed with the upgrade! I did and now KDE/KDM do not start. This is a major (but so far untriaged) problem. https://bugs.edge.launchpad.net/kubuntu-ppa/+bug/670788 and https://bugs.kde.org/show_bug.cgi?id=256025. Please wait for the affected packages to be fixed i.e. upgrade only when you don't get the message about some packages having to be removed.
