我正在尝试在Ubuntu 20.04 docker镜像上安装Erlang/Elixir，但是我卡在了一个要求选择地理区域的esl-erlang提示框上。我该如何静音或将默认值设置为US？
这是我的Docker镜像：
FROM ubuntu:20.04
ENV LANG=en_US.UTF-8
RUN apt-get update -y
RUN apt-get install -y wget gnupg2 inotify-tools locales && \
locale-gen en_US.UTF-8
RUN wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && dpkg -i erlang-solutions_2.0_all.deb
RUN apt-get update -y
RUN apt-get install -y esl-erlang
RUN apt-get install -y elixir
CMD ["/bin/bash"]
这是Docker卡住的提示：

如何关闭 esl-erlang 提示？
