Error Installing Unity3d deb package on Ubuntu 15.04

I attempted to download, and install the official 64-bit .deb package for Unity3d on a system with Ubuntu 15.04. Unfortunately, when I attempted to open the deb package in the Ubuntu Software Center, I received this error: "Cannot Install 'lib32stdc++6'"

Any suggestions? I had successfully installed the Unity3d deb package on an Ubuntu 14.04 system, but now with 15.04 it doesn't seem to be working.

Thanks in advance.

 

Hey Quantum

Did you try using a terminal? Just open up a terminal by pressing Ctrl+T, cd to your Downloads folder (assuming the deb is in there) and use this line: sudo dpkg -i #FILENAME OF DEB#. This will manually install your deb package.

The installer will probably fail due to some missing libraries. In this case, all those c++ libraries you need. If that happens, use this line: sudo apt-get install -f which will install all missing libraries and automatically presumes the installation of unity.

Good luck!
