Hello, I am currently running Ubuntu 20. However, when I was following the steps to install Ros2, I encounter a stranger error. Does anyone know how to resolve the following error?

shouyu@shouyu-Nitro-AN515-55:~$ sudo apt install ros-galactic-desktop

Can you try to sudo apt-get install ros-galactic-pcl-conversions ros-galactic-rqt-common-plugins ros-galactic-rviz-default-plugins ros-galactic-rviz2?

It should give you more information about what is missing currently in your setup. Please share it with us.

Did you use rosdep init and rosdep update in your ROS2 workspace?

Hello, thank you for taking time to answer the question.

So before I saw this answer, I did the hard way, which is to reimage my Linux, and reinstalled ROS2 on the new system.

Thank you very much for your time!

@sdu568 Well, I'd be lying if I said I hadn't done the same myself a few times, haha!
