This problem may appear in amd64 system trying to use i386 program. For me the problem solution is:
sudo apt-get install libcanberra-gtk-module:i386 libcanberra-gtk0:i386 If it does not work try reinstalling libcanberra-gtk0 AT YOUR OWN RISK. The uninstallation causes removing of possibly very important packets for You. Please analyze a packet list at step 2. If any problems after step 3 (power loss or bug) POSSIBLE YOU WILL HAVE A SYSTEM WITHOUT A DESKTOP. 1. Run but don't confirm at prompt [Y/N] sudo apt-get remove libcanberra-gtk0 2. Carefully analyze apt-get answer and find a list of packets to be removed. The lines maybe different from computer to computer. For example: Packets to be REMOVED: gnome-session-canberra gnome-session-fallback libcanberra-gtk-module libcanberra-gtk0 metacity ubuntu-desktop If You will not restore these packets possibly You will have great problems. 3. Copy this packet list to Your favorite text editor 4. Answer "Y" 5. Run the command after replacing <list> with saved list (with spaces between elements) of removed packets at step 3: sudo apt-get install <list> libcanberra-gtk0 For previous example sudo apt-get install gnome-session-canberra gnome-session-fallback libcanberra-gtk-module libcanberra-gtk0 metacity ubuntu-desktop libcanberra-gtk0 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libcanberra in Ubuntu. https://bugs.launchpad.net/bugs/872172 Title: libcanberra-gtk0 should recommend Gtk2 and Gtk3 module to fix: Gtk- Message: Failed to load module "canberra-gtk-module" Status in “libcanberra” package in Ubuntu: Triaged Bug description: Trying to run any Gtk 3 application in Oneiric, I am getting the following message/error: % ubuntu-bug Gtk-Message: Failed to load module "canberra-gtk-module" libcanberra-gtk-module only ships this file: /usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so When setting the GTK_PATH explicitly, it fails to load like this: % export GTK_PATH=:/usr/lib/gtk-2.0 % ubuntu-bug (apport-gtk:12816): Gtk-WARNING **: GTK+ module /usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so cannot be loaded.

Gtk-Message: Failed to load module "canberra-gtk-module" The fix/workaround appears to be installing libcanberra-gtk3-module, or removing libcanberra-gtk-module, which is only being installed as a recommendation for transmission-gtk (in this case): % aptitude why libcanberra-gtk-module i libcanberra-gtk0 Recommends libcanberra-gtk-module % aptitude search '?depends(libcanberra-gtk0)' | awk '{print $2}' balsa gnome-panel gnome-session-canberra gnubg gok libbrasero-media1 libcanberra-gtk-dev libcanberra-gtk-module libcanberra-gtk0-dbg libcheese-gtk18 metacity transmission-gtk wallch xchat-gnome I think that libcanberra-gtk0 should not only recommend the Gtk 2 module, but also the Gtk 3 one. So the "Recommends: libcanberra-gtk-module" should become "Recommends: libcanberra-gtk-module, libcanberra-gtk3-module".
