I've done something. Not sure what. If I run apt-get update followed by apt-get dist-upgrade all's fine. If I run apt-get update followed by apt-get dselect-upgrade, dselect wants to remove 197M of software and packages. How do I regenerate the packages list for dselect so that it will accept a dselect upgrade ?? This is a nasty surprise waiting to catch new users [and some old ones!] Andy
