Failed to load module "cranberra-gtk-module"

[catproof]

When running the Euroc example I get this:

• p1: 0.00019359000725671649
• p2: 1.7618711353861727e-05
• fps: 20
• color order: RGB (ignored if grayscale)

ORB Extractor Parameters:

• Number of Features: 1000
• Scale Levels: 8
• Scale Factor: 1.2000000476837158
• Initial Fast Threshold: 20
• Minimum Fast Threshold: 7

(process:2266): Gtk-WARNING **: 18:30:43.775: Locale not supported by C library.
Using the fallback 'C' locale.
Gtk-Message: 18:30:43.799: Failed to load module "canberra-gtk-module"
Gtk-Message: 18:30:43.800: Failed to load module "canberra-gtk-module"

The example still runs successfully. However, to make the 'Failed to load module..." message go away, I use the command:

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module
