OK. > apt-get upgrade > apt-get full-upgrade I personally tend to use: apt-get --purge dist-upgrade This takes care of purging the configuration files of packages that get removed (take care, of course, to not let it remove things you still need, like the old PostgreSQL version until the cluster(s) have migrated). > apt-get autoremove Again, add --purge here and take care (though etckeeper helps). > Now the system is really in a clean state with only debian12 packages > installed. Is it? Remember that apt doesn’t know about leftover conffiles. Try: dpkg -l | grep -v ^ii | cut -c 1-$COLUMNS This ought to show only the header and perhaps “held” packages (first column “hi”); if it also shows “rc” in the first column then you have leftover conffiles, which indeed can cause trouble; run “dpkg --purge pkgname pkgname…” to clean them up. bye, //mirabilos -- Infrastrukturexperte • tarent solutions GmbH Am Dickobskreuz 10, D-53121 Bonn • http://www.tarent.de/ Telephon +49 228 54881-393 • Fax: +49 228 54881-235 HRB AG Bonn 5168 • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg **************************************************** /⁀\ The UTF-8 Ribbon ╲ ╱ Campaign against Mit dem tarent-Newsletter nichts mehr verpassen: ╳ HTML eMail!
