After installed Ubuntu13.10, and i want to run a 32bit software, in the pass, you just run
sudo apt-get install ia32-libs
to install the 32bit library.
But in Ubuntu13.10, Canonical has decided to end support for the transitional package of ia32-libs. This will not allow 64 bit versions of this distribution (13.10) to access Secondlife. There are two methods given below, depending on how you updated.
After google, i found the solution. Details: http://wiki.phoenixviewer.com/ia32-libs-in-ubuntu-13-10
1. set the source of software center
see the detail on the image below
run these commands
sudo apt-get update
2. Install the necessary libraries.
sudo apt-get install libgtk2.0-0:i386 libpangox-1.0-0:i386 libpangoxft-1.0-0:i386 libidn11:i386 libglu1-mesa:i386
If you want sounds and streaming music (streaming media is still very iffy), install this gstreamer package:
sudo apt-get install gstreamer0.10-pulseaudio:i386
Done! Have fun with Ubuntu!
