Just install them. It's just a warning, not a fatal error. Ignore the warning and install the packages. Or you can add the key for the repository, if you want, and the warnings will go away,

Its not a warning after the dialog box opens I can't further install the application(there is just a OK option in the dialog box after it opens).Tell me how add the key for the repository.

If you have a problem with the software center, use Synaptic. There are instructions for installing repository keys in the wiki and on numerous threads on the forums. I no longer use Ubuntu, so I'm not certain how the software center works, but you should be able to go to the PPA, find a place to download the key, save it to your computer, then open the Software Sources tab in Edit Preferences, and click on Import Key File or something similar, then navigate to the key you downloaded.

try refreshing the package index files
close any software center/synaptic windows and run from a terminal (applications>accessories)


sudo apt-get updateand try again

You might also try downloading a program called ubuntu Tweak. It can be a helpfull shortcut to installing and managing software packages and ppa's
