Arch Linux

I have installed openfoam and it is installing paraview as dependency. I have also installed freecad which is installing vtk as dependency.
I am getting error when trying to run update.

installed packages:
local/openfoam 6.20190108-1
local/paraview 5.6.0-2
local/freecad 0.17.13544-9
local/vtk 8.1.2-2


I am getting this error:
