本文解决了在尝试恢复Ubuntu密码时遇到的问题。作者遵循了一个教程但未能成功，原因是系统启动为只读状态，导致passwd命令无法修改相关文件。通过运行'mount -rw -oremount /'命令将系统更改为读写模式后，问题得以解决。

Hi,

I faced the same problem when I tried to recover my Ubuntu password following the tutorial on:

http://www.psychocats.net/ubuntu/resetpassword

Looking for a solution, I read and try all the stuff from other forums where mainly they diagnose problems of inconsistency between /etc/shadow and /etc/passwd files, but that was not the problem. The problem was that the system was started as read only, so the passwd command cannot modify the above mentioned files. The solution was very simple. I ran the following command:

# mount -rw -o remount /

Then I just executed the passwd command with the corresponding username and it worked as charm. Try this before anything else. I hope it saves some time for somebody else.
