Inspired by the advice on this group and the -s option, I'm trying out aptitude. But I'm surprised by this:
$ aptitude -s upgrade Reading Package Lists... Done Building Dependency Tree Reading extended state information Initializing package states... Done Reading task descriptions... Done The following packages are unused and will be REMOVED: followed by a long list of packages, some of which I'm running right now. How does aptitude determine this list, and what's the best way to correct it? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
