One way to find out: sudo apt-get remove libsc7_2.3.1 It will remove all that depends on the package as well. Before doing it, it will ask if you are sure. Say no, or hit Ctrl-C, unless the package list looks totally harmless to you. > Also a naive question: why all those deb packages in /var/cache/apt/archives ? Probably to make reinstalling faster. I usually do sudo apt-get clean as a part of my weekly(?) update routine, and it seems to keep them away. Actually, my routine command (cut and pasted from the wiki page where I note the changes) is sudo apt-get update && sudo apt-get dist-upgrade -u && sudo apt-get clean -H -- Heikki Levanto "In Murphy We Turst" heikki (at) lsd (dot) dk -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
