[TomTorger]

I get the exact same error on ubuntu 20.04.

[vukor]

Same error on mac

[closedLoop]

Same as this issue: https://github.com/jupyterhub/jupyterhub-deploy-docker/issues/91

[HiloadProgrammer]

In Dockerfile.jupyterhub the line RUN /opt/conda/bin/conda install -yq psycopg2=2.7 updates the python version from 3.6.6 to 3.7.. Therefore you will get a similar error as Conda #9672: No module named 'conda' . To fix this issue I added the line `RUN echo "python 3.6." > /opt/conda/conda-meta/pinnedbefore I installedpsycopg2` to pin the python version.

[nrgpy]

@HiloadProgrammer this worked for me (and apparently 3 others). should i submit a pull request to have the Dockerfile.jupyterhub file updated, or is there another fix in the works?

@nrgpy I see this solution more as a quick fix rather than a permanent solution. Currently I am not working on this issue therefore there is no other fix that I know about.

If you like you can submit this fix.
