我尝试在Ubuntu 20.04 docker镜像上安装Erlang/Elixir，但是我被一个提示esl-erlang的地理区域挂起了。我该如何静音或者将默认设置为US？
这是我的Docker图像：

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"]

下面是Docker挂起的提示：
