Seems like you have some broken packages or dependencies. Try doing sudo apt-get update, if you get some error updating, try following:

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.backup
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update

and then try installing g++.

Always run sudo apt-get update then sudo apt-get install g++. The sudo apt-get clean command is optional. My install worked just fine without it.

Rather than just installing g++ or gcc it is more recommended to install the build-essential package.

You should install it with the following commands:

sudo apt-get update
sudo apt-get install build-essential

Those two commands should install all the basics needed by the system to build things.
