將 qmail 從 1.03-38 升級到 1.06-5
我有點苦惱。我試圖升級一個 chroot 的環境，似乎我在這個過程中破壞了 dpkg。
我不知道問題的原因是 apt-get 無法處理 qmail 升級還是其他原因（似乎 snmpd 在上一輪也沒有“完成”）。
我認為我要解決的錯誤是：
E: Sub-process /usr/bin/dpkg returned an error code (1)看來我有一個非常舊的 qmail 版本，升級到我的 apt 鏡像中的那個改變太大了。我用Google搜尋過，還沒有找到 1.03-38 和 1.06-5 之間的任何東西。
（刪除了幾行並在格式上苦苦掙扎）

我剛剛跑了這個：
dpkg --configure -a至少這讓我克服了 dpkg 的這個問題/錯誤。我迫切需要安裝一個自定義的 deb 包。
在嘗試安裝我的自定義 deb 包時，我收到了很多這樣的消息：
mycustompackage depends on libssl1.0.0 (>= 1.0.1t-1+deb7u1); however: Package libssl1.0.0:i386 is not configured yet.我猜我的最後一批更新檔不知何故以錯誤結束，dpkg 不會讓我做任何其他事情。
我的 qmail（可能還有 snmpd）問題仍然存在，但我現在只需要“修復”dpkg。
