    Software Center problem

    Every time I try to install a new program, I get the warning that it "Requires installation of untrusted packages". No matter whether I click on Repair or OK, it pops up again and again and I can't install anything.
    Thanks for your time.

    Open a terminal and enter:

    Code:
    sudo apt-get update
    And please post the output.

    You may need to add the key for any non-standard repositories you might have added. For example:
    Code:
    apt-key adv --recv-key --keyserver keyserver.ubuntu.com A040830F7FAC5991

    ibjsb4 Thanks. I tried that but it didn't solve the problem. I'm now updated though.

    Newbie user Thanks. Is that code exactly what I need to enter into the Terminal?

    jaspenhof2; Hi !

    I expect that the key code will be different...
    run in terminal:
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    I expect that in the out put of the "upgrade" command to have "W: GPG error:"
    Substitute that public key(s) -one at a time - into the above command sequence.

    Bashing-om I ran both of those sudos and yes, there was a "W:GPG error:" but I lost you at that point. I'm almost totally lost on this. Thanks for your time.

    apt-key adv --recv-key --keyserver keyserver.ubuntu.com A040830F7FAC5991

    Replace the red highlighted with the correct one associated with the gpg error.

    Edit: and yes, enter that in terminal

    Re: Software Center problem

    Tried the above. Still getting the error. Here's what I'm getting at the end of the update:

    W: a error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com raring Release: The following signatures were invalid: BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <ftpmaster@ubuntu.com>

    W: GPG error: http://us.archive.ubuntu.com raring Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>
    W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/raring/Release

    W: Some index files failed to download. They have been ignored, or old ones used instead.

    Thanks again.
