Ubuntu: Failed to load module "canberra-gtk-module"

[stem]

Hi,

I have an application built with Linux Mint 19.1 (gtk2). When I copy the executable to
a system with a fresh install of Ubuntu 18.04 and start it in a terminal, I get the message

Code: Pascal  [Select][+][-]

1. Gtk-Message: 21:02:50.761: Failed to load module "canberra-gtk-module"

The program starts and behaves normally.

In order to make the message disappear, I must run

Code: Pascal  [Select][+][-]

1. sudo apt install libcanberra-gtk-module

Can I ignore the message?

Thank you.

Hmmm ... I think you can ignore it but it's symptomatic of a problem in the Ubuntu configuration. Libcanberra is used to translate signals to event sounds and should have been installed automatically. This is what my system says about libcanberra-gtk-module:

Code: Bash  [Select][+][-]

1. lucamar@selene:~$ aptitude show libcanberra-gtk-module
2. Paquete: libcanberra-gtk-module
3. Estado: instalado
4. [...other info...]
5. Descripción: translates GTK+ widgets signals to event sounds
6.  A GtkModule which will automatically hook into all kinds of events inside a GTK+ program and generate sound events from them.
7. lucamar@selene:~$ aptitude why libcanberra-gtk-module
8. i   libcanberra-gtk0 Recommends libcanberra-gtk-module
9. lucamar@selene:~$ aptitude why libcanberra-gtk0
10. i   metacity Depends libcanberra-gtk0 (>= 0.2)
11. lucamar@selene:~$ aptitude why metacity
12. i   unity-2d Depends metacity (>= 1:2.34.1-1ubuntu8)
13. lucamar@selene:~$ aptitude why unity-2d
14. i   ubuntu-desktop Depends unity-2d

Note: You can ignore the step-reference to unity-2d; it's just an artifact introduced by an update.
