Fail to download gradle

  1. Summary of my problem

My goal is to have a Docker image for flutter based on OpenSuse (this OS is needed).
I was able to run git clone flutter to install flutter, but when I now try to create an app with

 flutter create hello

I get:

developer@fa00db6045df:~> flutter create hello

The original exception was: ProcessException: The command failed
  Command: tar -xzf

I am not sure what to try next.

Thanks for any help!
