    Root password prompt does not lauch

    Hello,
    I have upgraded to ubuntu 8.04 two week ago, and I am not able to launch any root privilege program because the root password prompt does not launch (looks like it is launching, but it never does).
    I have been looking in different forums for a bug or a solution, bu nothing.
    I would appreciate any idea.
    Thanks,
    Dotakon

    Do you mean that when you prefix a command by using sudo, nothing happens?

    Under Ubuntu the root password is locked and temporary root access is granted through the sudo command.

    This provides a much safer OS.

    In case you don't know sudo means super user do.

    Paste this command in the terminal:
    Code:
    gksudo synaptic
    If there are any error messages, please paste those back here.

    Looks like the common broken sudo problem. To confirm, Open a terminal (Applications-Accessories-Terminal) and give the command
    Code:
    sudo
    , you should get an error "Cannot resolve hostname". If you get this, it's easy to fix! Continuing in the terminal:

    Code:
    hostname
    Note the name shown.

    Then
    Code:
    gksu
    , and in the box that opens up, give the command as
    Code:
    gedit /etc/hosts
    and the user as root. Find the line with "127.0.0.1". The name following that number series should be EXACTLY the same as the hostname above. If it isn't change it, save, and quit. Note that you should have 2 entries for 127.0.0.1; one should have localhost, and the other should be exactly the same as the hostname command above.

    sudo should start working immediately.
