recommended post-install tasks for ubuntu and orca users?

[Jude DaShiell]

1) as root run updatedb to build and update the locate data base, 2) as
    root edit /etc/apt/sources.list and uncomment all repositories on the
    list, 3) as root run aptitude update to get a current data base of
    available packages, 4) as root run aptitude dist-upgrade to do an
    aggressive upgrade of as many packages to current versions as possible,
    5) as root do shutdown -h now and restart the system to take advantage
    of all of those updates, Anyone have items to add to this list?
