    can't download from software center.

    I am not able to download anything from Ubuntu software center.
    When I typed the command 'sudo apt-get update' in the terminal I got the following error.



    "W: GPG error: http://security.ubuntu.com oneiric-security Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

    What should I do?

    Hi, this is how to replace the GPG key error when installing packages.
    Code:
    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEYID
    and replace KEYID with the number shown in the error message.
    Thank you

    I have replaced KEYID with '40976EAF437D05B5' as it was in the error. Then I tried the command
    'sudo apt-get update' but then I got the following error.

    I would try a different server. Open the Software Center > Edit > Software Sources > change to a different one

    Re: Can't download

    Thanks for your advice.


    It's not like I can't open the software center, when I click the button 'Install' it gives messages

    "failed to download package files

    check your internet connection"

    and then,

    "Requires Installation Of untrusted Packages
    The action would require the installation of packages from not authenticated sources."

    and in details it gives"libcddb2 libdvbpsi7 libebml3 libiso9660-7 libmatroska4 libsdl-image1.2 libtar0 libupnp3 libva-x11-1 libvcdinfo0 libxcb-keysyms1 libxcb-randr0 libxcb-xv0 videolan-doc"

    What are untrusted packages and to what sources I should use so that computer will be safe?
