Trace not working, Paraview 5.7.0, Ubuntu 20.04.3

Hello, When I try to start a trace, I get the following errors:

ERROR: In /build/paraview-vlxewD/paraview-5.7.0/ParaViewCore/ServerManager/Core/vtkSMTrace.cxx, line 76
vtkSMTrace (0x555764841a00): Failed to import paraview.smtrace module.

Generic Warning: In /build/paraview-vlxewD/paraview-5.7.0/ParaViewCore/ServerManager/Core/vtkSMTrace.cxx, line 162
Trace not started since required Python modules are missing.

What can I do to start the trace tool?

Thank you.

please try with the last binary release: https://www.paraview.org/download/

I’ll try a newer release. If it works, I will need a remote server to install the same release because I would like to run Paraview in client/server mode. Thank you, Doug.
