    I am also having problem as above, the software sources tab doesn’t have any other options other than automatic. Would love any advise, I’m new to Ubuntu.

    I have a new Dell Inspiron Mini with Ubuntu 8.04 LTS
    I want to upgrade via 8.10 to 9.04 and then to 9.10
    However the Software Sources window only shows Automatic Updates so I get no further than Step 2
