OpenCVSharp runtime for Ubuntu 22.04 is not available. So you cannot make it work on Ubuntu 22.04.

But you can make it work on Ubuntu 18.04:

  1. Add OpenCvSharp4 and OpenCvSharp4.runtime.ubuntu.18.04-x64 packages to your custom task.
  2. Run: dotnet publish .\Wexflow.Tasks.MyNetCoreTask\Wexflow.Tasks.MyNetCoreTask.csproj --runtime ubuntu.18.04-x64 --configuration Release --force --output .\output (Replace Wexflow.Tasks.MyNetCoreTask with your custom task name)
  3. Copy/Paste Wexflow.Tasks.MyNetCoreTask.dll, OpenCvSharp.dll, libOpenCvSharpExtern.so and other dependencies from .\output to /opt/wexflow/Wexflow.Server
  4. Go to: cd /opt/wexflow/Wexflow.Server
  5. Run: ldd libOpenCvSharpExtern.so
  6. Install missing libraries
  7. Restart the server: sudo systemctl restart wexflow.service
  8. Save & Run your custom workflow
