Hi, <template> during a test with piuparts I noticed your package left unowned files on the system after purge, which is a violation of policy 6.8: http://www.debian.org/doc/debian-policy/ch-maintainerscripts.html#s-removedetails The leftover files are actually alternatives that were installed by the package but have not been properly removed. While there is ongoing discussion how to remove alternatives correctly (see http://bugs.debian.org/71621 for details) the following strategy should work for regular cases: * 'postinst configure' always installs the alternative * 'prerm remove' removes the alternative * 'postrm remove' and 'postrm disappear' remove the alternative In all other cases a maintainer script is invoked (e.g. upgrade, deconfigure) the alternatives are not modified to preserve user configuration. Removing the alternative in 'prerm remove' avoids having a dangling link once the actual file gets removed, but 'prerm remove' is not called in all cases (e.g. unpacked but not configured packages or disappearing packages) so the postrm must remove the alternative again (update-alternatives gracefully handles removal of non-existing alternatives). Note that the arguments for adding and removing alternatives differ, for removal it's 'update-alternatives --remove <name> <path>'. Filing this as important as having a piuparts clean archive is a release goal since lenny. </template> >From the attached log (scroll to the bottom...): 0m52.9s INFO: Warning: Package purging left files on system: /etc/alternatives/ttf-japanese-gothic.ttf -> /usr/share/fonts/opentype/ipaexfont/ipaexg.ttf not owned /etc/alternatives/ttf-japanese-mincho.ttf -> /usr/share/fonts/opentype/ipaexfont/ipaexm.ttf not owned /usr/share/fonts/ owned by: fonts-ipaexfont-mincho, fonts-ipaexfont-gothic /usr/share/fonts/opentype/ owned by: fonts-ipaexfont-mincho, fonts-ipaexfont-gothic /usr/share/fonts/opentype/ttf-japanese-gothic.otf -> /etc/alternatives/ttf-japanese-gothic.ttf not owned /usr/share/fonts/opentype/ttf-japanese-mincho.otf -> /etc/alternatives/ttf-japanese-mincho.ttf not owned Due to the package rename, the stuff in the preinst script is not being run at all during upgrades from squeeze: fonts-ipaexfont-* will always be a new install, so "$2" will be empty and all the dpkg --compare-versions "$2" lt-nl "$someversion" will evaluate to false. I'll add a patch once I get the bug number. It does two things: * Add preinst to the transitional packages to remove the alternative there. But there is really no guarantee for the transitional being installed at all ... but if it is installed, u-a won't emit a diagnostic about something dangling ... * fonts-ipaexfont-*.preinst: run the alternative cleanup on fresh installation to ensure the cleanup is run even if the transitionals are not used Please get this fixed in sid and unblocked for wheezy to fix this upgrade problem. I also offer (and intend to) to NMU fonts-ipaexfont to take care of this. cheers, Andreas
