    Thanks,

    The best repository info I could find on the web.

    good work

  • Eric Anderson

    You may also need to set up the GPG key for apt. If you get an error like the following when using the new repository,that’s what’s going on.

    “GPG error: http://archive.ubuntu.com dapper Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5″

    To correct this, retrieve the GPG key:
    $ gpg –recv-keys 40976EAF437D05B5
    And then add it to apt-keys:
    $ gpg –export –armor 40976EAF437D05B5 | sudo apt-key add -

    Thanks so much. Installed studio64 (debian distro) and was trying to add ubuntu sources.

    Eric, I don’t know if it was the form interface, but the long dashes in front of the gpg commands should be –
    gpg –recv-keys 40976EAF437D05B5
    gpg –export –armor 40976EAF437D05B5 | sudo apt-key add -

  • Gord Fisch

    Hey, it did it to me too. that’s not a long dash, it’s a double dash. I’ll try again:
    gpg – -recv-keys 40976EAF437D05B5
    gpg – -export –armor 40976EAF437D05B5 | sudo apt-key add -

  • pete greening

    but more importantly… what do I need to use as a keyserver to get this bad boy 40976EAF437D05B5

  • Krasimir Milchev

    And if you get:

    gpg –recv-keys 40976EAF437D05B5
    gpg: no keyserver known (use option –keyserver)
    gpg: keyserver receive failed: bad URI

    you need to explicitly say which is the key server:

    gpg –keyserver keyserver.ubuntu.com –recv-keys 40976EAF437D05B5

    Please remove this article from the *debianadmin* site or at the very least mark it that it shouldn’t be used by people running debian.

    People are adding these repos to their sources.list on debian machines and causing all manner of mess. Fortunately, most of the versions are sufficiently ancient that it at least causes little damage these days.

  • Suraj

  • mohamed

    can this methode make some problems to my OS (debian) ??

  • Tom

    It doesn’t work on Debian Squeeze, so it seems to be useless.
