run dotnet core with opencvsharp on ubuntu server 20.04 error

Question

The code works fine on macos and windows, but not sure why it cannot work on ubuntu server. I did follow some documentation from https://github.com/shimat/opencvsharp but so sad it not working, missing quite a lot of ".so" file after execute ldd libOpenCvSharpExtern.so

   System.DllNotFoundException: Unable to load shared library 'OpenCvSharpExtern' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libOpenCvSha>
