1).在启动项选择:Advaned options for Ubuntu.
2).然后 选择:Ubuntu ,with Linux 3.13.0-24-generic (recovery mode),
3). 等待加载完成..你将看到”Recovery Menu (filesystem state :read-only)”
4).选择root Drop to root shell prompt 就会进入单用户模式了..
然后是修改密码.
输入passwd user,回车后就出现
authentication token manipulation error.
passwd unchanged..
接下来我就在不断的尝试….
找了很多文章看…CSDN,网易的什么都有
后来找到了一篇外国人写的…

You probably encountered this error while trying to reset the password on a Ubuntu system.
root@u13-04:~# passwd nyuser
Enter new UNIX password:
Retype new UNIX password:
passwd: Authentication token manipulation error
passwd: password unchanged
This is the result of trying to work on a file system while mounted as read-only. The solution is a simple one. Before making changes to the users password mount the filesystem as read-write which allows for the necessary changes to be made.
mount -o rw,remount /
Now try to change the users passwords again.
root@u13-04:~# passwd nyuser Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
关键代码是:mount -o rw,remount / .
输入后就可以改了..注意..输入后什么也不会提示.
