所以我前几天试图升级Ubuntu 11.10 64位系统时遇到了一个错误：
dpkg: ../../src/archives.c:978: tarobject: 断言 `r == stab.st_size' 失败。
于是我按照这个Ubuntu论坛的帖子和这个帖子的方法进行操作。
我从info文件夹和status文件中移除了ubuntu-docs。
现在每当我尝试安装/删除/升级任何软件包时都会收到一个错误提示：
Traceback (most recent call last):

SystemError: E:I wasn't able to locate a file for the ubuntu-docs package. This might mean you need to manually fix this package.
当我尝试通过命令行安装
ubuntu-docs时，我得到了以下输出： BlockquoteReading package lists... Done

...看起来和我开始遇到问题时差不多，所以我查看了信息--没有ubuntu-docs包，但是状态中有一个条目，所以我将其删除并再次尝试，但是只要我运行sudo dpkg --configure -a，ubuntu-docs的条目就会重新出现。
有什么想法吗？
编辑 (不作为评论以保存格式):
这个帖子说我需要在从状态中删除相应的行后运行sudo apt-get update。所以我先运行sudo apt-get clean，然后再运行sudo apt-get update。但是我收到了一条消息：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
在运行了
sudo dpkg --configure -a之后，状态文件中包含以下内容：Package: ubuntu-docs
Status: install reinstreq half-installed
Priority: optional
Section: doc
Version: 11.10.4
不确定是否有帮助。
