tzdata freeze docker构建Swfit镜像

Question

在运行docker build构建快速镜像时，tzdata将停止该进程。它会提示选择一个位置，但在我输入号码后没有反应。

Configuring tzdata
------------------

    Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Etc
2. America     5. Arctic     8. Europe    11. SystemV
3. Antarctica  6. Asia       9. Indian    12. US
Geographic area: 

我的Dockefile是：

FROM ubuntu:18.04

    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

# Vapor setup
RUN /bin/bash -c "$(wget -qO- https://apt.vapor.sh)"

# Install vapor and clean
RUN apt-get install swift vapor -y \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

RUN vapor --help

在我重置Docker之前，它工作正常。我的错误在哪里？

通过在Dockerfile中添加ARG DEBIAN_FRONTEND=noninteractive来防止tzdata请求。
