昨天安装是Ubuntu Server. 配置好了几个软件后就忘记继续了...今天打开,居然忘记了密码...真是的.. 后来还是要改了. 不想重新弄什么的了..百度了下怎么改密码...然后就有一篇文章说是在进入系统前进入高级模式..然后里面有root的单用户模式..-----kohna, 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... http://linhost.info/2013/08/passwd-authentication-token-manipulation-error-ubuntu/ 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. 来自kohna. 2014-05-20-0:28 |
