build Dockerfile issue

Hi,
I tried to build Dockerfile but at the stage clone lava-packages and install, the command is failure.

Log: The command '/bin/sh -c /start.sh && git clone -b master https://git.linaro.org/lava/lava-dispatcher.git /home/lava/lava-dispatcher && cd /home/lava/lava-dispatcher && git clone -b master https://git.linaro.org/lava/lava-server.git /home/lava/lava-server && cd /home/lava/lava-server && echo "add build then install capability to debian-dev-build.sh" && echo "cd ${DIR} && dpkg -i *. deb" >> /home/lava/lava-server/share/debian-dev-build.sh && echo "Installing dispatcher & server" && cd /home/lava/lava-dispatcher && /home/lava/lava-server/share/debian-dev-build.sh -p lava-dispatcher && cd /home/lava/lava-server && /home/lava/lava-server/share/debian-dev-build.sh -p lava-server && /stop.sh' returned a non-zero code: 1

The specific error is: dpkg-checkbuilddeps: error: Unmet build dependencies: python3-sphinx (>= 1.0.7+dfsg) python3-setuptools (>= 3)
So please tell me how to solve this issue!!!
