我尝试复制此项目https://github.com/tabulapdf/tabula.git，此项目中存在dockerfile。我尝试从dockerfile构建映像，但在构建映像时出现错误，提示“无法连接到deb.debian.org：http：“
我试着在stackoverflow中搜索相关问题，但没有得到任何明确的想法如何解决这个问题。

FROM jruby:9.1-jdk

RUN apt-get update -qq && apt-get install -y build-essential
RUN echo 'gem: --no-rdoc --no-ri' >> /.gemrc

ENV GEM_HOME /usr/local/bundle
ENV PATH $GEM_HOME/bin:$PATH
RUN gem install bundler -v '< 2' \
  && bundle config --global path "$GEM_HOME" \
  && bundle config --global bin "$GEM_HOME/bin"

这是我得到的错误，而建立的形象：
