為什麼為不同的拱門安裝 libc6 不適用於 armhf？

我正在嘗試在已經啟用 i386 的 64 位系統上進行交叉編譯：

$ dpkg --print-architecture
amd64
$ dpkg --print-foreign-architectures
i386
armhf

僅啟用了 jessie 儲存庫：

$ 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

但是，我遇到了一個我無法解讀的奇怪衝突（“ libc6:armhf : Breaks: libc6 (!= 2.19-18+deb8u1)”），完整的 apt-get 輸出如下所示。

i386 libc 在這個系統上安然無恙，但是 armhf 版本（和 armel 就這個問題）失敗了。我如何看待這個 apt-get 錯誤以及如何修復它？

$ apt-get install libc6:armhf 讀取包列表…完成 建構依賴樹

讀取狀態資訊…完成 一些包無法安裝。這可能意味著您請求了一種不可能的情況，或者如果您使用的是不穩定的發行版，一些必需的軟體包尚未創建或已從 Incoming 中移出。以下資訊可能有助於解決這種情況：

libc6:armhf : Breaks: libc6 (!= 2.19-18+deb8u1) but 2.19-19 is to be installed

Debian multiarch 的規則之一是版本必須跨架構完全匹配。Debian jessie 有版本2.19-18+deb8u1，但不知何故你最終2.19-19安裝了 amd64（可能是 i386）。

我不知道您的系統最初是如何進入這種狀態的。也許在某個時候，您或以前的管理員將其更改sources.list為 testing，然後將其更改回 jessie。

從 snapshot.debian.org 下載 armhf 的 2.19-19 並使用 dpkg 手動安裝可能是一個解決方案。
