Comment 30 for bug 1016294

Note to Canonical devs.

dpkg previously read "foreign-architecture i386" in /etc/dpkg/dpkg.cfg.d/multiarch.

This key is no longer recognized by dpkg and I guess was consequently removed from Ubuntu.

dpkg now reads /var/lib/dpkg/arch

You can create /var/lib/dpkg/arch and place the two architectures in it:

amd64
i386

Verify the setup with dpkg --print-architecture and dpkg --print-foreign-architectures.

Please let us know if you plan to add this file to the dpkg package in an update to Quantal.

We'll set this by hand in Linux Mint to avoid any potential conflicts with a future update.

PS: I'm assuming this was overlooked or forgotten here. If multiarch was disabled in Quantal by design, please accept my apologies for the assumption.
