usb_cam stderr: usb_cam while installing from source in docker image

I am facing an error while building docker image and installing the usb_cam ros2 package from source. Following is my Dockerfile

FROM osrf/ros:foxy-desktop ARG ROS_DISTRO=foxy

ENV ROS_DISTRO $ROS_DISTRO RUN rm /bin/sh && ln -s /bin/bash /bin/sh

RUN apt-get update &&
apt-get -y install ros-$ROS_DISTRO-librealsense2

#create workspace

RUN source /opt/ros/$ROS_DISTRO/setup.bash &&
apt -y install libusb-1.0-0-dev build-essential python3-colcon-common-extensions python3-rosdep git libpython3-dev python3-pip &&
pip3 install -U argcomplete &&
mkdir -p /root/dev_ws/src &&
cd /root/dev_ws &&
rosdep update &&
colcon build

#build usb_cam from source RUN cd /root/dev_ws/src &&
source /root/dev_ws/install/setup.bash &&
git clone https://github.com/ros-drivers/usb_cam.git --branch ros2 &&
cd .. &&
apt update &&
rosdep install --from-paths src --ignore-src -r -y &&
colcon build

Getting following errors:

Make sure you call rosdep install before trying to build. It looks like you are building, then using rosdep install after
