I installed matlab 2019a with update3 on ubuntu 16.04 64bit. When I run matlab, I got output: Gtk-Message: 10:32:31.466: Failed to load module "canberra-gtk-module".
How to sort this problem.
Thanks in advance.

This is not working for me. When I type MATLAB from linux Ubuntu command window, what appears is failed ot load module "canberra-gtk-module" I follow the instructions in
https://www.mathworks.com/help/matlab/matlab_env/remove-canberra-gtk-module-and-pk-gtk-module-messages.html
however, in my /lib/x86_64-linux-gnu folder I see gtk-2.0, gtk-3.0, and gtk-4.0 . Which of these am I supposed to use????
Moving on, the answer here is a bit dated and overly specific without explaining how to generalize.
For example, I write export MATLAB_JAVA=/usr/lib/jvm/java-1.21.0-openjdk-amd64
This is because when I try to find where my ---- (I do not know is it is abin file? a run file? execuatable file? nonone tells)
The reason I type that is because from https://stackoverflow.com/questions/5251323/where-can-i-find-the-java-sdk-in-linux-after-installing-it I see that update-java-alternatives -l will tell you which java implementation is the default for your system and where in the filesystem it is installed.
I need help. Please MATLAB help me

So the answer is in a terminal excecute the following
sudo apt-get install libcanberra-gtk* libgconf-2-4
sudo ln -s /usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libcanberra-gtk-module.so /usr/lib/libcanberra-gtk-module.so
The second line will create a link to the module. Matlab works with gtk-2.0 module. For other linux distributions follow this.
Problem solved, at least for me.

Worked for matlab 2022b. But we use the command of 'sudo apt-get -y install libcanberra-gtk-module' to install libcanberra-gtk. The second step is important. Don't forget to create link under /usr/lib directory using the command uppon. If the Linux version and related gtk version is different, you should check it under the /usr/lib/*-linux-gnu/gtk-*.

I believe the canberra-gtk-module messages have no detrimental effect on MATLAB and can be ignored, but having said that...
To run MATLAB R2019a or R2019b on Ubuntu 16.04 LTS without the canberra-gtk-message:
You have three environmental variables that need to be set before running matlab
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0
export LIBOVERLAY_SCROLLBAR=0
export GIO_EXTRA_MODULES=/usr/lib/x86_64-linux-gnu/gio/modules
OR you can run matlab in the bash shell by typing:
$ GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 LIBOVERLAY_SCROLLBAR=0 GIO_EXTRA_MODULES=/usr/lib/x86_64-linux-gnu/gio/modules /usr/local/MATLAB/R2019a/bin/matlab
----
To run R2019a on Ubuntu 18.04 LTS without the canberra-gtk-message:
You need to install libcanberra-gtk-module and libgconf-2-4
You don't need to set any environmental variables.
----
To run R2019b on Ubuntu 18.04 LTS without the canberra-gtk-message:
you need to install libcanberra-gtk-module
You have one environmental variable that needs to be set before running matlab:
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0
OR you can run matlab in the bash shell by typing:
$ GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 /usr/local/MATLAB/R2019b/bin/matlab
Good luck.

I did: sudo apt-get install libcanberra-gtk-module libcanberra-gtk0. But the error message is still there.

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."

I tried the work around suggested in the "bug report" from the above link. Did not fix the problem. I can use the matlab as is with the error but irritating to keep the terminal open and running otherwise Matlab closes

I had the same error with my R2019b installation in ubuntu 19.10. After I installed the module with "sudo apt install libcanberra-gtk-module -y", if I call matlab from the command line with the cmd "LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0/modules:$LD_LIBRARY_PATH /usr/local/bin/matlab", the error message doesn't appear anymore.

Finally I solve this problem by change from 2019b to 2019a. The error message disappear. There must be something wrong with 2019b's Linux version.

It had the same message and then I followed @Scott Minkin recommandation and I still have a message, but a different one:

In both case Matlab 2019b is launched as expected but I am wondering if everything is ok because of the messages I keep having in the Terminal.
I am running Ubuntu 19.10. Thank you for your expertise.

Not sure why the pk-gtk-module warning is coming up. What is the value of $GTK_MODULES? And can you try blanking it out by setting GTK_MODULES=
GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 GTK_MODULES= matlab
Good luck.

I also get the same error message while running
Gtk-Message: 04:38:48.679: Failed to load module "canberra-gtk-module"
for Matlab R2020a on Ubuntu 19.10, it works slower than R2019b but untill now, during running the program, it does not give an another error.

Had the same problem on EndeavourOS (Arch-based). By looking through yay I saw that libcanberra was actually installed, but running again
yay -S libcanberra
solved the problem apparently. I have been using MATLAB R2024b Revision 5.

I learned that the two files libgtk-x11-2.0.so.0 supplied in /usr/local/MATLAB/R2019b/bin/glnxa64 are causing this issue. Simply removing them helped me:
cd /usr/local/MATLAB/R2019b/bin/glnxa64
sudo mkdir exclude
sudo mv libg*-x11-2.0.so.0 exclude/

After the above I still got:
Failed to load module "pk-gtk-module"
I found the required libpk-gtk-module file my gtk-3.0 module folder. Copying it to the Matlab folder clears this error message:
sudo cp /usr/lib64/gtk-3.0/modules/libpk-gtk-module.so /usr/local/MATLAB/R2019b/bin/glnxa64/
