How to get rid of the canberra-gtk-module error

Canberrra GTK missing

This is more like a "note to self":

The Problem:

I'm running Ubuntu 18.04 in an Oracle Virtual Box for radio experiments with the FL2k VGA adapter.
Gnuradio complained about a missing canberra-gtk module in startup. But I already had the canberra-gtk3 module installed.

The Solution:

It admittedly is a bit of a shotgun solution. I simply did a:

sudo apt-get install libcanberra-gt*

and that was that.
