This is not a bug, but wrong settings in your configuration.
You have enabled a PPA https://launchpad.net/~thefanclub/+archive/ubuntu/grive-tools but this PPA does not provide software packages for the Ubuntu release that you are running; this leads to error messages.
You have to disable that PPA from your list of repository sources.
