GTK is a toolkit used for creating GUIs. Most of the default Ubuntu desktop, and the GNOME desktop environment, is developed using it. The "libcanberra" is a library for playing sounds.
- The "libcanberra-gtk-module", then, is the module that takes GUI events from GTK+ (like pressing a button, or minimizing a window) and plays some configured sound.
Workaround/Solution:
- You can refer to the following link that suggests installing the missing packages to fix this issue. https://www.mathworks.com/support/bugreports/details/1995075#fix_options
- You can try executing one of the following commands to install gtk modules if the above EBR step is not working for you.
$ sudo apt install libcanberra-gtk*
$ sudo apt install libcanberra-gtk-module:i386
$ sudo apt-get install libcanberra-gtk-module
$ sudo apt-get install libcanberra-gtk3-module
- If you still face the issue, the final step is to install the recent updates for your OS.
