Unable to launch paraview: Could not load the Qt platform plugin


I am trying to install ParaView-5.9.1-MPI-Linux-Python3.8-64bit on Ubuntu 20.04 LTS on a Windows10 machine. When I enter ./paraview in the bin directory, it returns:

qt.qpa.xcb: could not connect to display
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.

error: exception occurred: Child aborted

Can you tell me how to fix it?

WSL is not supported, use the windows release downloaded from:


But the windows release would become like this when I loaded an exodus file

Intel bug, see here for solutions:

You need to install the xcb libraries (should be libxcb-x11 in Ubuntu).
