problem: docker run to run ROS in a new docker container about unity-robotics-hub

[peifeng-unity]

Hello @eeGeoGZP,

Thank you for bringing this issue up. The error seems to show that the "server_endpoint.py" contains DOS carriage return "\r", which cannot be executed in the Ubuntu system inside the docker.

To address the issue, we will need to add a line in Dockerfile to convert line breaks in all the executable files, like https://github.com/Unity-Technologies/Unity-Robotics-Hub/blob/add-dos2unix-in-dockerfile/tutorials/pick_and_place/docker/Dockerfile#L19.

We will go and merge the fix. If you need to have it work in the meantime, you can just follow the above Dockerfile and rebuild the docker image.

Please let us know if your problem could be resolved with the fix?

Thank you,
Peifeng

Hi Peifeng, I have added the line RUN /bin/bash -c "find $ROS_WORKSPACE -type f -print0 | xargs -0 dos2unix" at the line #19 as you mentioned. After rebuilt the docker image, "docker run ------" is running ok (without error). Thank you.
