我有点麻烦。我尝试升级 chroot 环境，但似乎在此过程中破坏了 dpkg。
我不知道问题的原因是否是 apt-get 无法处理 qmail 升级或者是其他原因（似乎 snmpd 在最后一轮中也没有“完成”）。
我认为我要解决的错误是：
E: Sub-process /usr/bin/dpkg returned an error code (1)
看来我的 qmail 版本太旧了，升级到 apt 镜像中的版本变化太大了。我在 Google 上搜索过，但尚未找到 1.03-38 和 1.06-5 之间的任何版本。
（删除了几行并且调整了格式）
# apt-get install qmail

答案1
我刚刚运行了这个：
dpkg --configure -a
至少这让我解决了 dpkg 的问题/错误。我迫切需要安装自定义 deb 包。
当我尝试安装自定义 deb 包时，我收到了很多这样的消息：
mycustompackage depends on libssl1.0.0 (>= 1.0.1t-1+deb7u1); however:
Package libssl1.0.0:i386 is not configured yet.
我猜我的最后一批修补不知何故以错误结束，并且 dpkg 不允许我做任何其他事情。
我的 qmail（可能还有 snmpd）问题仍然存在，但我现在只需要“修复” dpkg。
