Failed to load module canberra-gtk-module

Check the green box with the tip at Home · Gtk.jl
It says:

On some platforms, you may see messages like

Gtk-Message: 20:15:48.288: Failed to load module “canberra-gtk-module”

These are harmless. If you want to suppress them, on Unix platforms you can add something like

export GTK_PATH=$GTK_PATH:/usr/lib/x86_64-linux-gnu/gtk-3.0

to your .bashrc file. (You may need to customize the path for your system; it should have a modules directory containing libcanberra.)
