Maybe, the fact that APT tries to not remove any of your currently installed packages during an upgrade. There is not a "standard" to make a package to disappear, but there is something you can do to ensure that "apt-get upgrade" works: Just make emacs-goodies-extra-el a dummy (empty) package which depends on emacs-goodies-el, and make debbugs-el a dummy package which depends on debian-el. Make them of extra priority and section oldlibs. Remove the conflicts, so that these packages are actually installed. Then "apt-get upgrade" will actually upgrade all the packages. After the upgrade, dpkg --purge `deborphan` (which almost everybody usually does anyway) should remove the dummy packages. If you don't do that the user will have to read the release notes to see which packages he/she should upgrade by hand, but that would be a shame: the release notes are for things which we weren't able to fix before the release. My "ideal" of release notes is like this: -----------------------------cut here---------------------------------- To upgrade from woody to sarge, follow the usual procedure: apt-get update apt-get upgrade apt-get dist-upgrade -----------------------------cut here---------------------------------- If the ordinary tools to upgrade the system are not enough to upgrade the system and the release notes are longer than that, I think it's a clear sign that we have made something wrong. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
