linux-映像-泛型似乎被破坏了。

Question

我用的是Ubuntu12.04。最近我不能再安装任何东西了。我总是收到以下错误消息：

Setting up linux-image-3.2.0-34-generic (3.2.0-34.53) ...
Running depmod.

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

dpkg -C的输出是：

The following packages have been unpacked but not yet configured.
They must be configured using dpkg --configure or the configure menu option in dselect for them to work:
 linux-image-generic  Generic Linux kernel image
 linux-generic        Complete Generic Linux kernel

The following packages are only half configured, probably due to problems configuring them the first time. The configuration should be retried using dpkg --configure <package> or the configure menu option in dselect:
 linux-image-3.2.0-34-generic Linux kernel image for version 3.2.0 on 32 bit x8

但是dpkg --configure linux-image-3.2.0-34-generic linux-image-generic linux-generic会产生以下错误消息：

如果有人能帮我解决这个问题，我会很高兴的！

不知何故，您有一个伪造的pwd (打印工作目录)命令。我看了一下postinst脚本中引用的行。它试图“保存”工作目录，方法是将pwd的输出存储在变量中，然后在引用的行中，在执行其他目录中的一些操作后切换回该目录。这个问题的发生是因为被调用的pwd的输出是空的。

运行命令which pwd。如果输出不是/bin/pwd，找出原因并修复它。
