macos - 从 Dockerfile 构建 Docker 镜像的问题

Question

我的任务是使用 ubuntu:18.10 从我自己的 Dockerfile 创建一个 docker 容器，并在这个容器中运行 pdflatex。我的系统是 MacOs，我的 Dockerfile 是这样的:

FROM ubuntu:18.10

RUN apt-get update && apt-get install texlive-fonts-recommended \
    texlive-generic-recommended \
    texlive-latex-extra \
    texlive-fonts-extra \
    dvipng \
    texlive-latex-recommended \
    texlive-base \
    texlive-pictures \
    texlive-lang-cyrillic \
    texlive-science \
    cm-super \
    texlive-generic-extra

CMD ["bash"]

我在终端中输入这一行，同时位于 Dockerfile 所在的目录中:

docker build .

我得到的输出是这样的:

据我了解，为 pdflatex 安装包时出现问题，但我不明白错误是什么以及如何修复它。你能告诉我该怎么做吗？

默认存储库已弃用。
将/etc/apt/sources.list 中的存储库 *.ubuntu.com 替换为 old-releases.ubuntu.com，如下所示(这是整个 Dockerfile):

FROM ubuntu:18.10

RUN sed -i 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
RUN sed -i 's/security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

RUN apt-get update && apt-get install -y texlive-fonts-recommended \
    texlive-generic-recommended \
    texlive-latex-extra \
    texlive-fonts-extra \
    dvipng \
    texlive-latex-recommended \
    texlive-base \
    texlive-pictures \
    texlive-lang-cyrillic \
    texlive-science \
    cm-super \
    texlive-generic-extra

CMD ["bash"]

请注意，我添加了 -y到 apt-get install命令，因为我想自动同意安装。
