Date: Tue, 16 Aug 2011 11:46:39 -0700 From: Steve Langasek <[email protected]> To: [email protected] Subject: Multiarch in Oneiric for developers Dear developers, As part of the work to eliminate ia32-libs in favor of multiarch library installation (https://blueprints.launchpad.net/ubuntu/+spec/foundations-o-multiarch-next-steps), i386 sources have been enabled by default on amd64 systems in oneiric. For new installs, this is done by default in alpha-3 and above; and as of today, update-manager also ensures that i386 multiarch support is enabled by default on upgrade from natty. If you have upgraded to oneiric amd64 *before* today, or if you did an oneiric amd64 install prior to alpha-3, you will want to manually enable multiarch support on your system to ensure you get the same experience (and see the same packages) as other users. This is as simple as running the following command as root: # echo foreign-architecture i386 > /etc/dpkg/dpkg.cfg.d/multiarch An apt-get update later, and you'll have access to the full array of i386 packages in addition to the amd64 ones. Work is still ongoing to optimize the Packages file download time, which has obviously increased now that we're downloading Packages files for two architectures instead of one. Developers concerned about the impact on the speed of 'apt-get update' *can* choose to leave multiarch disabled for now. However, the next step on the roadmap now that this is enabled by default is to start chopping away at ia32-libs and removing its reverse-dependencies from the archive on amd64, which means that some packages (in particular, packages in multiverse and the Canonical partner archive) will no longer be available or usable on amd64 without i386 support enabled.
