I have installed everything these answers recommend. However, the problem is still there.

You must install:

sudo apt-get install packagekit-gtk3-module

and

sudo apt-get install libcanberra-gtk-module

See bug reports:

https://www.mathworks.com/support/bugreports/details/1995075

"On some Linux distributions, a message appears in the terminal window when starting MATLAB:

Gtk-Message: <timestamp>: Failed to load module "canberra-gtk-module"

and/or

Gtk-Message: <timestamp>: Failed to load module "pk-gtk-module"

This message is informational and has no effect on MATLAB."

[Robin T. Bye]

I have the problem with the canberra-gtk-module.

1. The message is more then informational since it causes Matlab failing to start and a segmentation fault.
2. The advice on the Mathworks bug report page replicates similar advice on various internet sites but does not work (same error despite installing the packages relating to the modules).

[Jan Studnicka]

Your problem can be caused by something different. In my case this message appears and MATLAB starts normally.

I suggest you contact support:

[Brian Zelenke]

I think you need to set the GTK_PATH environment variable as described at https://www.mathworks.com/matlabcentral/answers/472134-gtk-message-10-32-31-466-failed-to-load-module-canberra-gtk-module.

On Ubuntu this would be:

export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0

On RedHat (RHEL) this would be:

export GTK_PATH=/usr/lib64/gtk-2.0/

[yoshitomo kaneda]

Thank you very much !!!

It works for my environment. (CentOS 7.9.2009)

[Mark Thomas]

This is the only change needed for MATLAB R2020a (Update 1 and Update 6) on CentOS 6.6 [yes, I know!]:

No need to play around with GTK 3.

Just add an /etc/profile.d/gtk2.sh script, setting:

GTK_PATH=/usr/lib64/gtk-2.0
export GTK_PATH

This lets MATLAB find the /usr/lib64/gtk-2.0/modules directory, which holds both modules.

BTW: I found the "R2020a_Update_1_Linux.iso" graphical installer would not run, so had to use ./install -inputFile <name> to do a scripted install. (The GUI opened OK, got to the "Enter File Installation Key" page but would not let me type into the FIK box or press the [Next] button.)

Applying this fix before running ./install might let the graphical installer run, too.
