Command line tool for removing orphaned packages?

deborphan

  • Man page
  • The command deborphan itself will display a list
  • If you wish to see all the packages which aren't required you can run:

    deborphan --guess-all
    
  • You do not need root privileges to use this tool, it reads the installed package lists and it won't remove any packages itself, merely tell you what it thinks you should remove

Installation

sudo apt-get install deborphan

Just for the those users that do not use command line: Ubuntu tweak tool is a graphical front end that also installs deborphan.
