Actually, --purge-unused isn't even needed, and this may be seen as even worse, because this could be more surprising for the user, and more difficult to detect the issue and its cause. # aptitude install tracker-extract will remove tracker-extract, but not purge it, so that the /etc/systemd/user/gnome-session.target.wants/localsearch-3.service symbolic link is still there. But later (immediately after or much later), the user may want to purge tracker-extract for cleanup: # dpkg --purge tracker-extract And this time, this removes the above symbolic link. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
