mhh@mhh-virtual-machine:~ python3 -c "import fenics" Traceback (most recent call last): File "<string>", line 1, in <module> ModuleNotFoundError: No module named 'fenics' mhh@mhh-virtual-machine:~

Take each line of what is in the docker file, remove the &&\ on every line, and run them sequentially, ie

RUN apt-get update &&\
    apt-get install -y software-properties-common && \
    add-apt-repository ppa:fenics-packages/fenics && \
    apt-get update &&\
    apt-get install -y fenics

Becomes

apt-get update
apt-get install -y software-properties-common
add-apt-repository ppa:fenics-packages/fenics
apt-get update
apt-get install -y fenics

I run these commands. then, I have opened Pycharm, but when I run the code I face this error:

You do not have the correct version of ufl installed.

Please uninstall the local ufl installation

You should not reinstall fenics-ufl. It comes with the apt-Get installation
