ERROR: failed to solve: process "/bin/bash -o pipefail -c conda install pytorch && fix-permissions \"${CONDA_DIR}\" /home/${NB_USER}" did not complete successfully: exit code: 1

Attempted to fix by adding lines

RUN conda config --remove-key channels && \
    conda config --add channels defaults && \
    conda config --add channels conda-forge && \

But no good

I thought this was handled, but @casperdcl can confirm.

Hmm it might be some demo/example/excercises environment.yml

[KrisThielemans]

@casperdcl presumably this can be closed?
