我尝试将 VirtualBox 虚拟机移动到 Docker 映像。我们使用 VirtualBox 交叉编译 armhf 设备的源代码（基于 BeagleBone 的东西）
我遇到了问题RUN apt-get install -y build-essential:armhf
完整的 Docker 代码如下所示：
FROM debian:jessie
RUN apt-get update
RUN apt-get upgrade
RUN apt-get install -y build-essential module-assistant curl git cmake
RUN curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
RUN echo "deb http://emdebian.org/tools/debian jessie main" > /etc/apt/sources.list.d/crosstools.list
RUN dpkg --add-architecture armhf
RUN apt-get update
RUN apt-get install -y crossbuild-essential-armhf
RUN apt-get install -y curl:armhf
RUN apt-get install -y libcurl4-openssl-dev:armhf openssl:armhf
RUN apt-get install -y build-essential:armhf
RUN apt-get install -y libssl-dev:armhf
运行 docker build 时出现以下错误：
Step 12/13 : RUN apt-get install -y build-essential:armhf
---> Running in ca5a82d30cc7

The command '/bin/sh -c apt-get install -y build-essential:armhf' returned a non-zero code: 100
如果我查看虚拟机上的 bash 历史记录，它看起来是一样的。我的 Docker 代码有什么问题？

Done
答案1
这是导致问题的行：
RUN apt-get install -y build-essential:armhf
您不需要build-essential:armhf交叉编译。你应该删除它；docker build然后应该能够毫无问题地构建容器。
答案2
看起来有些依赖项无法安装。具体是什么很难说。
不幸的是，apt当遇到无法修复的问题时， 的输出并不是很有帮助。不过，您可以诱使它提供更多输出——通过-o Debug::pkgProblemResolver=yes在 apt 命令行上指定。这应该会为您提供有关它正在尝试做什么的更多详细信息，并希望允许您修复它。
如果这不能解决您的问题，请使用该选项运行 apt 并发布输出。
