This seems like a network connection issue during the docker build.

This seems like a network connection issue during the docker build.这似乎是Docker构建过程中的网络连接问题。

i had already solved this problem. but i meet another problem "UID changed to: 0 User name changed to: root usermod: user 'root' already exists chown: cannot access '/home/root': No such file or directory Fixing inconsistent case in filenames."

This means that you are running things as root. You should not do that. Run them as your local user. You will have to add your user to the docker group. These issues are not related to holoocean_ros.

forgive me,i meet the problem again

when i run "./build_all_from_src.sh",the terminal show "[3039/3039] UnrealBuildTool.exe UE4Editor-Linux-Debug.target Total time in Local executor: 2766.98 seconds Total execution time: 2902.39 seconds UID changed to: 1000 User name changed to: zb Error: [Errno 13] Permission denied: '/holoocean/holooceanvenv'"

could you please tell me the reason for the error and what should i do next? best wishes for you

Try this on your host:

sudo chown -R zb:zb /path/to/holoocean

Where /path/to/holoocean is the folder where you checked out the source repositories.

Thank you again for your reply，that's useful but when i run './build_all_from_src.sh holoocean_sim_build' the terminal show in the last

'Successfully installed sonar-data-processor-1.0 Starting >>> hoveringauv_thruster_control Starting >>> py_ros2_holoocean Starting >>> sonar_data_processor Finished <<< py_ros2_holoocean [1.65s] Finished <<< hoveringauv_thruster_control [7.20s] [9.427s] WARNING:colcon.colcon_cmake.task.cmake.build:Could not run installation step for package 'sonar_data_processor' because it has no 'install' target Finished <<< sonar_data_processor [7.80s] Summary: 3 packages finished [8.76s]'

I don't know if this installation was successful.

and i try to run './run_holoocean_test.sh' An error has occurred: 'Traceback (most recent call last): File "", line 4, in File "/holoocean/holooceanvenv/lib/python3.10/site-packages/holoocean/holoocean.py", line 103, in make return HoloOceanEnvironment(**param_dict) File "/holoocean/holooceanvenv/lib/python3.10/site-packages/holoocean/environments.py", line 216, in init self._client.acquire(self._timeout) File "/holoocean/holooceanvenv/lib/python3.10/site-packages/holoocean/holooceanclient.py", line 101, in acquire self._get_semaphore_fn(self._semaphore2, timeout) File "/holoocean/holooceanvenv/lib/python3.10/site-packages/holoocean/holooceanclient.py", line 84, in posix_acquire_semaphore sem.acquire(timeout) posix_ipc.BusyError: Semaphore is busy'
