Failed to download dependencies

Hi, I had the same issue, and I manage to solve it with the following steps

  1. sudo apt-get install build-essential clang-3.9 git cmake ninja-build python3-requests python-dev tzdata sed curl wget unzip autoconf libtool
  2. sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/lib/llvm-3.9/bin/clang++ 100
  3. sudo update-alternatives --install /usr/bin/clang clang /usr/lib/llvm-3.9/bin/clang 100
  4. run ./Setup.sh again

Hope this helps
