Bitmask is not working after installation

Good evening (or morning ) everyone.
After a lot of pain I manage to install bitmask (open source network encryption) , point is now hen I run from command line I am getting this window

http://i.imgur.com/PHxl4t9.pngAfter I tried to run program as root but then I got

 sudo bitmask
+] launching bitmaskd...
QXcbConnection: Could not connect to display 
Removing stale pidfile /root/.config/leap/bitmaskd.pid

I m guessing problem is related to Qt , but I have fresh install python-qt5
.How to solve this issue and what is the problem ??
Thanks

You can not run a GUI program as root in that way. Use kdesu or gnomesu.

Thanks for response I used **gnomesu **and got the same result (windows which shows init.py files).
Any advice???

Maybe ask there:
