What is the planned status of Multiarch support in 11.10? In AMD64 Alpha 1, I attempted to install the i386 google chrome package using dpkg. The install failed citing architecture mismatches, Is support for this kind of install planned or am I missing something?


Install 32-bit Compatibility Libraries

Have you tried installing the 32-bit libraries?

sudo apt-get install ia32-libs

If that's installed, then navigate to the Chrome .deb package and use (to force installation):

sudo dpkg --force-architecture -i <name-of-package>.deb

And if things aren't working at first, try re-configuring the package manager:

sudo apt-get install -f


sudo dpkg --configure -a

Download Native 64-bit Google Chrome

Alternatively, you can just install the native 64-bit Chrome package from here at Google.

Just remember that Oneiric is still in Alpha, many things can go wrong; don't be surprised if it doesn't work initially!

  • Thanks for the dpkg info, I need to use a 32-bit browser to support the Juniper VPN which only works with a 32 bit browser/plugin – Mark Bidewell Jun 20 '11 at 14:48
  • @Mark, glad to help. And as Jorge posted, Multi-arch will appear natively (hopefully soon) instead of through abstraction libraries. Sorry, I missed that bit of the question :S – Alex Stevens Jun 20 '11 at 23:05

The plans for multiarch support in Oneiric are here:

(It could likely be broken in the Alpha)


Multiarch is supported pretty well at this point (last time I tried was Beta 1). It's just that a package must be build with support for Multiarch. You can see whether a package was built for Multiarch by checking it dependencies for the multiarch-support package.

For a more in-depth answer on Multiarch, see Is it possible to have 32 bit libraries installed on a 64 bit system?


When I updated to Oneiric, I lost the ability to exec 32 bit bins. I was able to find the ia32-libs-multiarch package, which was what ultimately got me back and running.

Curiously, aptitude install ia32-libs-multiarch led to some grotesque and unexpected dependency issues (particularly, it broke on libmysqlclient16.) Using the old apt-get did the trick, however.
