error message from update manager

Asked by KKevin901

During this morning system update. The Update Manager pops up a message window saying "An error occured" with the following details:

"W: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 60D11217247D1CFF"

I redo the update manually again and the same error window pops up again. Would like to seek for advise what should be done or just disregard this message.

Thanks in advance.

 Add the keys so open a terminal (Applications>Accessories>Terminal) and add the key for the first one with:
Code:

gpg --keyserver keyserver.ubuntu.com --recv 60D11217247D1CFF
gpg --export --armor 60D11217247D1CFF | sudo apt-key add -

then for the 2nd one do almost the same
Code:

gpg --keyserver keyserver.ubuntu.com --recv 6AF0E1940624A220
gpg --export --armor 6AF0E1940624A220 | sudo apt-key add -

then run
Code:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
