File has unexpected size

[KKAlexKK]

Hello

I had been successfully using a USB CAM with ROS2 until the update 2-3 days ago.

1. However, after the weekend, when I tried to use it again in the same way, I encountered the following errors: File has unexpected size and etc.

2. nvv4l2 has been bypassed and installed using v4l-utils

3. colcon build : cmake error (magic enum)

4. Additionally, through GPT, I managed to change the release to 3.1 and somehow access the Docker container. However, I kept failing to run colcon build due to missing packages such as gxf and image, which I had never seen before. (ros-humble-gxf-isaac-tensorops, ros-humble-isaac-ros-image-proc)

While I appreciate the version upgrade, existing users or new users might face difficulties using it. Therefore, if possible, could you test the installation from scratch by following the tutorial to ensure it works?

Also, if the issues I summarized below can be resolved by simple modifications, please provide detailed instructions on how to fix them.

Thank you in advance for your help.

For the File has unexpected size error in my case, it may be fixed through running sudo apt update in the container.
