heroku - apt-get无法使用docker + dokku中的自定义source.list来找到软件包

Question

我在启动Dokku应用程序时尝试使用apt-get安装软件包时遇到麻烦。

快速上下文:

我与Dokku一起使用的Buildpack，<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 /etc/apt/sources.list和 /etc/apt/sources.list.d中没有源存储库，因此我在 Heroku Apt buildpack的基础上构建了允许使用自定义源列表的功能。 Here是自定义的buildpack，而 here是我通过添加 sources.list来允许自定义 Sourcefile的特定更改。

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-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:

但是，仍然不高兴，因为 apt-get install仍然无法找到我要安装的软件包:

有任何提示/帮助吗？非常感谢!

只需使用自定义Dockerfile即可解决。在某个时候，我将花费更多时间来了解使用dokku-apt buildpack的问题。
