    Trouble installing or updating software in Kubuntu 12.04

    I just installed Kubuntu 12.04, and I've been trying to install updates (with Muon Software Updater) or add software (with Muon Software Center). However, most of the time both programs fail to ask for a user password before installing and then an error comes up saying the operation failed because I didn't provide authentication, even though it didn't ask for a password. Any help is appreciated.

    This command will call for your password and then update the system. That should get around the update issue with the gui tools.

    then
    Code:
    sudo apt-get upgrade
    And I believe this will bring your OS up to the most recent release.

    I like to see an explanation to go along with the instructions for the new reader who happens across a set of instructions like this.

    I count myself among those who need a reminder.

    And carl4926 and others on the system with the knowledge, I appreciate your being there. Thank you.

    upgrade
    upgrade is used to install the newest versions of all packages
    currently installed on the system from the sources enumerated in
    /etc/apt/sources.list. Packages currently installed with new
    versions available are retrieved and upgraded; under no
    circumstances are currently installed packages removed, or packages
    not already installed retrieved and installed. New versions of
    currently installed packages that cannot be upgraded without
    changing the install status of another package will be left at
    their current version. An update must be performed first so that
    apt-get knows that new versions of packages are available.

    The most recent release would need:
    dist-upgrade

    Along with changed sources....
