Well the conventional wisdom would be that without the preferences file, apt-get would try to upgrade all your files to a completely different (and Alpha quality) version of Ubuntu. If you let apt-get do this, this would probably break your system horribly... However, in this case it would probably be safe to do with without the preferences file for two reasons: 1) The Ubuntu GUI Upgrade Managers would allow you to uncheck the unwanted upgrades anyway. 2) We are removing the karmic sources afterwards anyway, so it would be unlikely that Ubuntu would install these unwanted updates later. I chose this way, because the first described way with update/upgrade > didn't work on my pc. I must have made a mistake, since it should work on any 9.04 Ubuntu system. Oh well, your way seems more user friendly anyway. -- John C. McCabe-Dansted PhD Student University of Western Australia
