Connection failed

By following the README.md and running the docker build command docker build . -f .\wslsp.Dockerfile -t wslsp, there are multiple failures which seem caused by connecting to http://security.ubuntu.com/ubuntu. Can anyone share ideas how to debug/resolve this failure?

The build log message is below:
