我正在尝试在已启用 i386 的 64 位系统上进行交叉编译：
$ dpkg --print-architecture
amd64
$ dpkg --print-foreign-architectures
i386
armhf
仅启用 jessie 存储库：
$ apt-cache policy libc6:armhf
libc6:armhf:
Installed: (none)
Candidate: 2.19-18+deb8u1
Version table:
2.19-18+deb8u1 0
700 http://http.debian.net/debian/ jessie/main armhf Packages
然而，我遇到了一个奇怪的冲突，我无法破译（“ libc6:armhf : Breaks: libc6 (!= 2.19-18+deb8u1)”），完整的 apt-get 输出如下。
i386 libc 在这个系统上运行得很好，但是armhf 版本（以及armel）失败了。我该如何看待这个 apt-get 错误以及如何修复它？

答案1
libc6 : Breaks: libc6:armhf (!= 2.19-19) but 2.19-18+deb8u1 is to be installed libc6:armhf : Breaks: libc6 (!= 2.19-18+deb8u1) but 2.19-19 is to be installed
Debian 多架构的规则之一是版本必须跨架构完全匹配。 Debian jessie 有版本2.19-18+deb8u1，但不知何故你最终2.19-19安装了 amd64（大概还有 i386）。
我不知道你的系统最初是如何进入这种状态的。也许在某个时候，您或以前的管理员将其更改sources.list为测试，然后将其更改回杰西。
从 snapshot.debian.org 下载 armhf 的 2.19-19 并使用 dpkg 手动安装可能是一个解决方案。
