    Raring update from beta


    I have been running 13.04 beta for a while and whenever I run an update, the last few lines of the update process look like this
    Reading package lists... Done
    W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: raring Release: The following signatures were invalid: BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <>
    W: Failed to fetch  
    W: Some index files failed to download. They have been ignored, or old ones used instead.
    Can anyone please tell me what a GPG error is, why it is not desirable and how I can go about fixing it. Thanks

    Re: Raring update from beta

    GPG errors are related to missing Launchpad GPG keys for all the PPAs you have added to your software sources. If you want to know about GPG keys, please see this: The GNU Privacy Handbook

    To fix it, run these commands at a terminal window:
    sudo apt-get clean
    cd /var/lib/apt
    sudo mv lists lists.old
    sudo mkdir -p lists/partial
    sudo apt-get clean
    sudo apt-get update
