Some requirement checks failed. You must fulfill these requirements before
You can read this in the oracle documentation :
This can occur if the DISPLAY variable is not set, or the user running the installation is not authorized to open an X window. For instance, if you use an su command to change from a user that is authorized to open an X window to a user account that is not authorized to open an X window on the display, such as a lower-privileged user opening windows on the root user's console display.
To troubleshoot this issue, run the command echo $DISPLAY to ensure that the display variable is set to the correct visual or to the correct host. If the display variable is set correctly then either ensure that you are logged in as the user authorized to open an X window, or run the command xhost + to allow any user to open an X window.
