  • I think that there is no specified protocol and for that reason it cannot open the display/GUI. Try "sudo apt purge gparted && sudo apt install gparted" (without the quotes). "sudo apt purge " deletes the package and its files permanently & "sudo apt install " installs the package. – na-no. Nov 05 '17 at 11:25
  • @pomsky you are correct!, that was the problem! cheers! – Lakshan Dissanayake Nov 05 '17 at 17:51

Yup pomsky, you are correct!!! Thanks!

Why don't gksu/gksudo or launching a graphical application with sudo work with Wayland?

xhost si:localuser:root 
sudo gparted
xhost -si:localuser:root
