[ROS2] setup_ubuntu20.04.sh not working

[hayato-m126]

I tried to setup ros2 branch, but I got erros below.

Error

$ ./setup_ubuntu20.04.sh ... TASK [autoware : Autoware (install gdown to download some files for neural network)] *** fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unable to find any of pip2, pip to use. pip needs to be installed."} ...

$ colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release --catkin-skip-building-tests colcon: Command not found

why

• Python2 pip is not installed.
• Colcon is not installed with ros2 binary.
