Operating system:Ubuntu LTS 16.04  
Slicer version: 4.11.0-2020-06-01  
Expected behavior: run the executable  
Actual behavior: I does not execute and appear the following message:

qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.  
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.
