password unchanged & Authentication token manipulation error

ubuntu下使用passwd问题记录

解决方法

sudo su 获得root身份后在使用刚才的passwd命令重新设置密码就搞定了。

出现错误

1. passwd: Authentication token manipulation error
2. passwd: password unchanged

hert@hert-T440p:~$ sudo passwd ftp_hert 
Enter new UNIX password: 
passwd: Authentication token manipulation error
passwd: password unchanged

切换到root

hert@hert-T440p:~$ su root
Password: 
su: Authentication failure

设置root密码

hert@hert-T440p:~$ passwd root
passwd: You may not view or modify password information for root.

hert@hert-T440p:~$ sudo  passwd root
Enter new UNIX password: 
passwd: Authentication token manipulation error
passwd: password unchanged
