    Question NO_PUBKEY error when checking for updates

    I fired up Update Manager and I checked for updates and I get this error:

    and I tried
    sudo apt-key adv --keyserver --recv-keys 531EE72F4C9D234C
    but this gave me THESE errors:

    and I have no idea how to fix this. I assume the second error is because of my internet connection, but that's an assumption. I think I should try again later and by running the code above I should get this error sorted out right?

    I know this is not thing you are looking for,but maybe to remove that ppa from source list and try to add it again with key.Just suggestion.
    There is no greater religion than a truth.
