Introduction :
To support GUI installers on Linux need to make sure the system has required libraries and X11 display.

Missing Libraries :
Missing the libXtst/libXrender RedHat Package Manager (RPM) which is required for a GUI install.

In the Linux host, there is only the x64 (64 bits) version of libXtst/libXrender library installed.You have to install the i686 (32 bits) version of the library
Both version must be installed (32 and 64 bits),Install the libXtst/libXrender RPM and its dependencies.

Ex:
# rpm -qa libXtst
libXtxt-1.2.3-1.el7.x68_64

$ rpm -qa libXtst
libXtst-1.2.3-1.el7.x86_64 (64 bits)
libXtst-1.2.3-1.el7.i686 (32 bits)

Enable X11 Forwarding :

X11 forwarding allows a user to start up remote applications, and then forward the application display to their local Windows machine. It enables you to run GUIs from a local server.

1.Open the SSH daemon configuration file. $ sudo vi /etc/ssh/sshd_config.
2.Locate and uncomment or change line X11Forwarding to be X11Forwarding yes.
3.Restart SSH daemon.

Want to use sudo:

Sometimes launching the Installer as root, not as local user, will get this unsupported GUI error message.when you have a requirement that the installer be run as root,
Issue this command before launching the installer,
xhost +si:localuser:root

xhost adds users to your Access Control List of your currently logged on GUI session. xhost + allows anyone, both remote and local, to access your current GUI session. The ACL is only modified for your current logged on session and gets cleared when you log out or reboot.
