Could anyone give me a reply to this question: I would like to have Google gadgets added to my Precise(12.04) Operating System. Is this possible? There is only this ppa: ppa:googlegadgets/ppa located here:

I would install them in synaptic:
deb hardy main
deb-src hardy main

If I use command-line,
sudo add-apt-repository ppa:googlegadgets/ppa
I get a 404 error
