I believe this was an experimental feature that was never officially supported

[AndreaCensi]

@afdaniele that is a very old version of the shell, right?

[afdaniele]

@david-boles where did you get the instructions about the duckietown/duckietown-shell image? As @CourchesneA said, it was an experimental feature and it was never officially released. You should install the shell via pip, preferably using PowerShell if on Windows.

@afdaniele They might have got the instructions here: https://hub.docker.com/r/duckietown/duckietown-shell, in the Installation on Docker (experimental) section.

@david-boles In case you still want to run your command, you may try using my image: jasonhu5/duckietown-shell:latest, I built it with dts 5.1.6. In your original running command, just replace the duckietown/duckietown-shell:latest with mine.

tl;dr Below are the steps I did to create the above image (just for reference). Could have used a Dockerfile, but not sure if all of this is proper.

I figured that the duckietown-shell docker image has python2, so it's not easy to directly use that image to upgrade dts. But luckily, it seems creating a new image is not hard.

For reference, here are the steps I did to create the docker image (with reference to this Dockerfile duckietown/duckietown-shell's Dockerfile on Docker Hub)

1. On my local machine: docker run -it --rm --network host docker:18-dind /bin/sh

2. Then WITHIN the container:

apk --update --no-cache add \
python3 \
python3-dev \
py3-pip \
bash \
git \
build-base \
musl-dev \
linux-headers

, and then pip3 install -U --user --no-cache-dir duckietown-shell (The numpy build does take QUITE A WHILE)

3. Then OUTSIDE of the container: docker ps and copy the ID of the above running container.

4. Finally, also OUTSIDE of the container: docker commit -c "ENV PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/root/.local/bin" copied_container_ID [repository[:tag]]

@jasonhu5 Thanks! We'll try it at some point.

@afdaniele We just got the Docker command from the README. See #66 for why we had trouble running it on Windows directly, though not installing it from Powershell might have been the issue (besides not being able to install docker at all on some computers).
