我在ubuntu上安装ldap-account-manager的时候出错，
当sudo aptitude install ldap-account-manager
出现如下错误：
- Reading package lists... Done
- Building dependency tree
- Reading state information... Done
- Reading extended state information
- Initializing package states... Done
- Building tag database... Done
- The following NEW packages will be automatically installed:

- The following NEW packages will be installed:

- Need to get 108kB of archives. After unpacking 868kB will be used.
- Do you want to continue ? [Y/n/?] y
- Writing extended state information... Error!
- E: I wasn't able to locate file for the ldap-account-manager package. This might mean you need to manually fix this package.
当我sudo dpkgdpkg -i ldap-account-manager2.4.all.deb
出现如下错误：
- Selecting previously deselected package ldap-account-manager.
- (Reading database ... 44030 files and directories currently installed.)
- Preparing to replace ldap-account-manager 2.4.0-1 (using ldap-account-manager2.4.all.deb) ...

- dpkg: error while cleaning up:

- Errors were encountered while processing:

这时候，
apt-get remove --purge，apt-get -f install
都不管用了
后来看了一人的解决方案，甚是感激啊。
其实就是将dpkg的status删除，我怎么就没有想到呢？
首先，确定以下命令不能用
- sudo aptitude update
- sudo aptitude -f install
然后，确定以下命令不能用
- sudo dpkg --force all --remove
如果都不行，恭喜你，你的dpkg真的有问题了。
现在开始
1、备份你的dpkg的status
sudo cp /var/lib/dpkg/status ~/backup/dpkg/
2、编辑status文件
sudo vim /var/lib/dpkg/status
3、查找你出问题的软件包，在本文中就是万恶的ldap-account-manager
在vim中
/ldap-account-manager

- 6493 aliases and MAC addresses. There is a tree viewer included to
- 6494 allow access to the raw LDAP attributes. You can use templates
- 6495 for account creation and use multiple configuration profiles.
- 6496 Account information can be exported as PDF file. There is also
- 6497 a script included which manages quotas and homedirectories.
- 6498 Homepage: http://lam.sourceforge.net/
4、全删除整个关于ldap-account-manager的package，保存退出
5、保证格式
保证下一个package和上一个package中间有一行空行。
6、现在已经找不到ldap-account-manager包了，重新安装。当然aptitude已经可以正常使用了。
