E: Some index files failed to download. They have been ignored, or old ones used instead.
The command '/bin/sh -c apt-get update   && apt-get install -y curl unzip   && rm -rf /var/lib/apt/lists/*' returned a non-zero code: 100

maybe needs update for base image & all dependent steps thereafter, for newer version of Debian.
