Can't start "add-ons" on Matlab R2023a on Debain12.

Hello,

The Matlab R2023a was installed on my computer successfully. But as the "add-ons" was clicked, there were errors:

Warning: X does not support locale en_US.UTF-8

Error using matlab.internal.cef.webwindow

MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: 127

Error in matlab.internal.webwindow/createImplementation (line 319)

implObj = matlab.internal.cef.webwindow(varargin{:});

Error in matlab.internal.webwindow (line 163)

obj.impl = obj.createImplementation(varargin{:});

Error in matlab.internal.addons.AddOnsWindow (line 41)

obj.webwindow = matlab.internal.webwindow('about:blank', obj.debugPort);

Error in matlab.internal.addons.Explorer/createNewWindow (line 111)

obj.addOnsWindowInstance = matlab.internal.addons.AddOnsWindow(obj.WINDOW_TITLE, clientType, obj.windowStateUtil.getPositionForExplorer);

Error in matlab.internal.addons.Explorer/show (line 61)

obj.createNewWindow;

Error in matlab.internal.addons.launchers.showExplorer (line 140)

matlab.internal.addons.Explorer.getInstance.show(navigationData)

What is the reason? Thanks.

The warning message can be ignored; see https://www.mathworks.com/matlabcentral/answers/1925710-warning-x-does-not-support-locale-en_us-utf-8#answer_1192075

But that does not explain the failure to launch.

Unix error 127 often means "command not found" at the shell level.

Is there a way to launch the "add-ons"?

Sorry, I do not know.

My guess would be that you are having problems with conflicting DLLs, such as libC.so.6 . However, it has been many years since I installed MATLAB onto Linux, and that was not a problem at the time.

Thanks. You help me a lot.

I had the exact issue and discovered your post. The solution was posted over here and it worked for me.

TL;DR in the $MATLABROOT/bin/glnxa64 folder, remove the symlink for libfreetype.so.6 and make a new symlink that points to this one: /usr/lib/x86_64-linux-gnu/libfreetype.so.6

Good find, @Darryl

Thanks for your kind reply. Your answer is right. After having checked the link in your answer, I don't know what to do, but your words

TL;DR in the $MATLABROOT/bin/glnxa64 folder, remove the symlink for libfreetype.so.6 and make a new symlink that points to this one: /usr/lib/x86_64-linux-gnu/libfreetype.so.6

let me know what should I do. I just

sudo ln -sf /usr/lib/x86_64-linux-gnu/libfreetype.so.6 libfreetype.so.6 

And the problem gone.

Thanks.
