apt-get 无法在 docker+dokku 中使用自定义 sources.list 定位包

Question

我在启动 Dokku 应用程序时尝试使用 apt-get 安装软件包时遇到问题。

快速上下文：

我正在与 Dokku 一起使用的构建包，<the-app>/.buildpacks:

https://github.com/auricapps/heroku-buildpack-apt
https://github.com/heroku/heroku-buildpack-python

我要安装的软件包，<the-app>/Aptfile：

libxml2-dev
libxmlsec1-dev
libxslt1-dev
pkg-config
python3-dev
zlib1g-dev

在故障排除中，我注意到源存储库在 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中不可用，因此我在 Heroku Apt buildpack to allow the use of a custom source list. Here is the custom buildpack, and here 的基础上进行了特定更改以允许自定义sources.list 通过添加 Sourcefile.

我包括的来源，<the-app>/Sourcefile：

deb http://archive.ubuntu.com/ubuntu trusty main restricted
deb-src http://archive.ubuntu.com/ubuntu trusty main restricted
deb http://archive.ubuntu.com/ubuntu trusty-updates main restricted
deb-src http://archive.ubuntu.com/ubuntu trusty-updates main restricted
deb http://archive.ubuntu.com/ubuntu trusty universe
deb-src http://archive.ubuntu.com/ubuntu trusty universe
deb http://archive.ubuntu.com/ubuntu trusty-updates universe
deb-src http://archive.ubuntu.com/ubuntu trusty-updates universe
deb http://archive.ubuntu.com/ubuntu trusty multiverse
deb-src http://archive.ubuntu.com/ubuntu trusty multiverse
deb http://archive.ubuntu.com/ubuntu trusty-updates multiverse
deb-src http://archive.ubuntu.com/ubuntu trusty-updates multiverse
deb http://archive.ubuntu.com/ubuntu trusty-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu trusty-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu trusty-security main
deb-src http://security.ubuntu.com/ubuntu trusty-security main
deb http://security.ubuntu.com/ubuntu trusty-security universe
deb-src http://security.ubuntu.com/ubuntu trusty-security universe

问题：

然而，仍然没有快乐，因为 apt-get install 仍然回复说无法找到我要安装的软件包：

有任何提示/帮助吗？非常感谢！

仅使用自定义 Dockerfile 即可解决。在某些时候，我会花更多时间来了解使用 dokku-apt buildpack 的问题是什么。

FROM heroku/cedar:14
ARG secret_key
RUN curl https://github.com/gliderlabs/herokuish/releases/download/v0.3.26/herokuish_0.3.26_linux_x86_64.tgz \
        --silent -L | tar -xzC /bin
RUN /bin/herokuish buildpack install \
    && ln -s /bin/herokuish /build \
    && ln -s /bin/herokuish /start \
    && ln -s /bin/herokuish /exec
COPY . /app
RUN bash /app/include/default_user.bash && rm -f /app/include/default_user.bash
RUN apt-get -qq -o dir::etc::sourcelist=/app/include/sources.list update \
  && apt-get -qq -o dir::etc::sourcelist=/app/include/sources.list -y --force-yes install \
    libxml2-dev \
    libxmlsec1-dev \
    libxslt1-dev \
    pkg-config \
    python3-dev \
    zlib1g-dev
