Installed GParted but it's not opening

I tried to open GParted after installing it, as it was not preinstalled in Ubuntu Gnome 16.10, but it just asked for root password but didn't open.

Then I tried to open from terminal and it showed this

jp@JP-PC:~$ sudo gparted

But it didn't start. I also tried restarting computer. Can anyone tell what's the problem with it. Thank you.

The issue is there in Ubuntu 17.10. Solved it by running the following command:

xhost +local:
