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：

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：

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

6489 Description: webfrontend for managing accounts in an LDAP directory
6490 LDAP Account Manager (LAM) runs on an existing webserver.It manages user, group
6491 and host accounts. Currently LAM supports these account types:
6492 Samba 2 and 3, Unix, Kolab 2, address book entries, NIS mail
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.

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。
