Cannot import name 'Mesh' from 'dolfin' (unknown location)

[Jonathan_Frutschy]

Well now Spyder can’t even find dolfin:

There is an unresolved post on this exact issue:

No module named 'dolfin' ubuntu 20.04

Hi, I am trying to install fenics2019.2 in my Ubuntu 20.04 machine. I followed the following instructions: sudo apt-get install software-properties-common sudo add-apt-repository ppa:fenics-packages/fenics sudo apt-get update sudo apt-get install --no-install-recommends fenics It got install successfully but when I try to import fenics, I am getting this error message: ModuleNotFoundError: No module named ‘dolfin’ [image]

I cannot reproduce any example without being able to import dolfin. Any idea on what to do?
