Description of the problem
It is not possible to install Skype, Google Earth or any 32-bit application in Linux Mint 14 RC 64-bit.
Cause of the problem
The ability to install 32-bit applications in a 64-bit environment is commonly referred to as “Multiarch”.
An upstream change occurred in Debian’s dpkg which made the Multiarch configuration in Ubuntu obsolete. That configuration was removed and Ubuntu 12.10 consequently released with Multiarch disabled by default.
The problem wasn’t detected during QA and impacts the two 64-bit editions of Linux Mint 14 RC.
