Error when building a new image from jupyterhub/singleuser:3.0.0

Hi, I’m trying to build a new docker image using jupyterhub/singleuser:3.0.0 as base image. This is the Dockerfile:

FROM jupyterhub/singleuser:3.0.0
RUN mamba install --quiet --yes \
    'tensorflow' && \
    mamba clean --all -f -y && \
    fix-permissions "${CONDA_DIR}" && \
    fix-permissions "/home/${NB_USER}"

However I’m facing the following errors:

Step 2/12 : RUN mamba install --quiet --yes     'tensorflow' &&     mamba clean --all -f -y &&     fix-permissions "${CONDA_DIR}" &&     fix-permissions "/home/${NB_USER}"
 ---> Running in a3bc1398de47

        api_ctx = api.Context()

Any idea on how to fix this?


Your example Dockerfile built successfully for me. Are you running into an operating system error?

I tried on two different systems: in both cases it works with singleuser v2.3.0, but not with 3.0.0

Which docker version are you using?

Issue fixed by upgrading Docker to the latest version.
