MathWorks Product Installer does not start on Ubuntu 20.04.3 LTS

I am trying to install MATLAB 2021b on Linux Ubuntu 20.04.3 LTS (Focal Fossa) running Linux Kernel 5.11.0-37-generic. I have downloaded matlab_R2021b_glnxa64 that contains the installer file. When I execute "sudo ./install" the installer does not show-up and the terminal stays stuck executing this command. However, I can see the installer process is up and running using the htop command.

The only way to stop it is by executing the following:

sudo killall -s 9 MathWorksProductInstaller

If I run the installer without the sudo previlage, it runs without any issue. However, it does not allow me to install MATLAB inside /usr/local directory nor create a symbolic link and that is why I want the sudo previlage.

Any reason why this happening with this new version of MATLAB?

This problem seems to be particular to MATLAB 2021b release as it does not happen with 2020b and 2021a releases.

Try running the following code in terminal (from ./install directory):

xhost +SI:localuser:root

Thanks @Gurpreet Singh it worked. Would you mind explaining the command?

After I've excuted the command, I got the following response:

localuser:root being added to access control list

Yeah it worked for me too using that command
