+To continue the installation, we should have access to the UI.
+If the OS does not have an UI, we should add the support for it:
+<code>
+sudo yum groupinstall "GNOME Desktop"
+sudo yum groupinstall "Graphical Administration Tools"
+sudo systemctl enable graphical.target
+sudo systemctl start graphical.target
+sudo systemctl set-default graphical.target
+sudo systemctl reboot
