on ubuntu sudo won't run the install file

I'm trying to install MatLab on Ubuntu 20.04.

Running

./install

in the terminal does bring out the installation window but then the installer doesn't have the permission to write on usr/local

So i need to run

sudo ./install

but this does nothing, the process doesn't do anything and doesn't stop. It doesn't even have an error message.

I've tried changing the permissions on the file with chmod but it doesn't anything.

Where could the problem come from ?

I've got the exact same problem in Kali 2021.3

I got an email from installation support (don't know why they didn't answer this thread) and this was their advice :

"" This appears to be an issue with MATLAB R2021b under root not being able to access the X Server. As a workaround, please try the following:

Launch Terminal

Type the following in the terminal to allow the root user to access the running X server:

   xhost +SI:localuser:root

After running the command above try running the installer "sudo ./install ""

I didn't use it tho, i chose to install inside of the home directory without sudo, it's a bit impractical as the software is not recognized by the UI but i can run it from terminal.

Running the following code in terminal (from ./install directory) worked for me:

xhost +SI:localuser:root
