I've just installed MATLAB 2019b on a new install of Ubuntu 18.04 LTS.
One application I run is called SPM. From what I can glean from the web, these errors are MATLAB issues.
The "Failed to load module "canberra..." error happens when SPM starts.
The other "Pango-CRITICAL..." errors happen after I click a button on SPM's interface.
MATLAB hangs after printing the errors, and I have to kill it.
Does anyone know of a fix?

Contact the authors of that toolbox for a resolution.
Note that thier website states,
For other platforms [other than Windows], you will need to build the MEX files using a suitable C compiler and the Makefile provided with the SPM distribution.

Hi,
It appears to be that 'libcanberra-gtk-module' doesn't exist or is corrupted. Installing or reinstalling the same would solve the issue. To install or reinstall the same on Ubuntu, the following terminal commands may be used:
Install:
sudo apt-get install libcanberra-gtk-module
Reinstall:
sudo apt-get install --reinstall libcanberra-gtk-module
Hope this helps!

Hi,
the gtk-module should not be a problem. Unfortunatly the pango critical issues prevents me too to use the SPM12 toolbox on my ubuntu 19 with Matlab 2019b.

by the way SPM12 loads on ubuntu 19.10 but the issue is present in ubuntu 20.4. When I try to load SPM12 I get a similar error:
Gtk-Message: 20:50:03.779: Failed to load module "canberra-gtk-module"

Still I have not found any solution to the problem.

Hi, the SPM mailing list suggested me to follow this link. I’ll try the fix and see if it works.

Dear all,
I found an easy fix. Before launching SPM12 just luanch the following command. It solved the problem for me!
#first command to launch
setenv('SPM_HTML_BROWSER','0')
#and after that
spm
