gazebo version : harmonic

I am trying to build a 4WD robot using ros2 and gazebo to simulate it ,I’ve been following this tutorial on YouTube https://www.youtube.com/watch?v=9Cl6utP-xig and I’ve created a package to launch gazebo and control the robot but I get this error when launching the launch file
ros2 launch project_bot gazebo.launch.py
[INFO] [launch]: All log files can be found below /home/asti/.ros/log/2025-04-22-13-26-21-449342-asti-HP-290-G4-Microtower-PC-6294
[INFO] [launch]: Default logging verbosity is set to INFO
[ERROR] [launch]: Caught exception in launch (see debug for traceback): Caught multiple exceptions when trying to load file of format [py]:

  • PackageNotFoundError: “package ‘gazebo_ros’ not found, searching: [‘/opt/ros/jazzy’, ‘/home/asti/project files/project_ws/install/vision_opencv’, ‘/home/asti/project files/project_ws/install/project_bot’, ‘/home/asti/project files/project_ws/install/opencv_tests’, ‘/home/asti/project files/project_ws/install/image_geometry’, ‘/home/asti/project files/project_ws/install/gazebo_msgs’, ‘/home/asti/project files/project_ws/install/gazebo_dev’, ‘/home/asti/project files/project_ws/install/cv_bridge’]”

I’ve noticed that the gazebo ros pkg is missing and tried to install it so i did
sudo apt install ros-jazzy-gazebo-ros-pkgs
and I got this massage E: Package ‘ros-jazzy-gazebo-ros-pkgs’ has no installation candidate
then I tried to install it from source by following this page Gazebo : Tutorial : Installing gazebo_ros_pkgs (ROS 2)
also didn’t work
I’m stuck in this for two weeks now and I need to finish this project by the end of May for a graduation project so if any one have some knowledge ,any help will be appreciated
