The official Ubuntu page for Google Earth says this:
Note to 64bit users: The 64bit debian package depends on ia32-libs which is deprecated and no longer available as of 13.10 Saucy. Use the 32bit package and multiarch-support.
Where is this multiarch-support and how can I ensure it is installed?
This is for a re-installation of the 64-bit version. The Software Updater lists http://dl.google.com/linux/earth/deb/stable main under the 'Other Software' tab. Does that mean multiarch-support is set to update as part of that?
