Since Ubuntu 13.10 Google earth cannot be installed out of the box on Ubuntu 64-bit systems because it requires the deprecated ia32-libs package. The previous solution I wrote about, for Ubuntu 13.10, did not work this time. I got Google Earth to run, but it crashed all the time.
I then found the googleearth-package which downloads the latest stable Google Earth installer from Google and creates a package for you. You can then install and remove the created package at will.
But the easiest solution, found on the Ubuntu documentation, turned out to be to:
1) install a number of dependencies, which you can do by running the following command from the command line (Of course, if you prefer, you can install them through the software centre or the synaptic package manager as well):
sudo apt-get install libc6-i386 libglib2.0-0:i386 libsm6:i386 \ libglu1-mesa:i386 libgl1-mesa-glx:i386 libxext6:i386 \ libxrender1:i386 libx11-6:i386 libfontconfig1:i386 lsb-core
2) download the google earth installation file from Google (make sure to select the .deb package for your CPU architecture, which I assume 64-bit since other wise there would be no point for you reading this post ;-).
3) install it using the Ubuntu Software Centre (you can simply double click the downloaded deb file).
4) Happy exploring 🙂
