"apt clean" removes unnecessary download packages. My personal preference is to have upgrade packages downloaded automatically but not installed, and to get a daily email message from each box in my house with a list of what is ready. After I do an upgrade, I also do a clean. At work, the local repo syncs with Debian mirrors, then tells the sysadmin team what's new. They push packages into each of several tiers of machines: the "any time" machines which can, if necessary, be rebooted mid-day; the "evening" machines which can stop after people have gone home; the "weekend" machines which need to wait for a maintenance window unless there is an emergency. -dsr-
