passwd：身份驗證令牌鎖忙

我正在ASUS Chromebook Flip使用Google Chrome OS 53.0.2773.3.dev：

chronos@localhost / $ cat /etc/os-release

chronos@localhost / $ uname -a

chronos@localhost / $ 

我正在嘗試更改 root 密碼，我得到以下資訊：

chronos@localhost / $ sudo passwd root
Enter new UNIX password: 
Retype new UNIX password: 
passwd: Authentication token lock busy
passwd: password unchanged
chronos@localhost / $ 

任何想法為什麼？和/或如何處理它？

根據這個連結，你需要使用sudo chromeos-setdevpasswd。

檢查根文件系統是否以讀寫模式掛載；如果沒有，請執行mount -o remount,rw然後重試。

例如，我在 從已經證明可行的恢復模式重置root密碼時收到此錯誤。init=/bin/bash經過一些論壇研究，結果發現我只是忘記了儲存新密碼並使用exec /sbin/init.
