/usr/bin/env: 'python': No such file or directory

System Information

This was the default behavior when I pulled the docker image to a new dev machine. I'm no docker expert, but I'm wondering if the FROM ubuntu:bionic in the Dockerfile isn't specific enough and the bionic base image was updated and it removed the 'python' symlink?

If I add RUN ln -s /usr/bin/python3 /usr/bin/python to the Dockerfile and rebuild the image /usr/bin/env python works again and I can use the scripts again.
