MATLAB: Do I get an error relating to X11 when using the Silent Installer for MATLAB on Linux

MATLAB

When running the silent installer on a Linux machine without an X server I get the following error:
java.lang.InternalError: Can't connect to X11 window server using 'localhost:0.0' as the value of the DISPLAY variable.

I thought the silent installer could run without an X Server. How can I run the silent installer without X11?

Best Answer

This issue occurs if you do not have an X Server installed and you have the DISPLAY environment variable set. This variable should not be set if you do not have an X Server installed.
To resolve this issue you can unset the DISPLAY variable and restart the installer. The installer should then complete successfully.
