我有一台装有 17.10 的笔记本电脑，已更新所有版本。它正在使用全盘加密
我今天刚刚更新到 18.04。一切顺利，最后它要求我重新启动，所以我就照做了。
启动时，系统提示我输入 luks 密码，无法成功。控制台告诉我
No key available with this passphrase.
我觉得一定是内核版本的问题。用以前的内核测试过，没有帮助。
我也对 18.04 和 17.10 live usb 进行了测试，但是没有成功：

关注此话题https://www.saout.de/pipermail/dm-crypt/2012-September/002735.html检查我的 luks 标头是否健康。没有发现任何可疑的东西。
我当然对密码很有信心。
关于如何进行有什么提示吗？

你应该尝试回答这个问题：Ubuntu 全盘加密 - 升级至 18.04 后密码错误
它对我有用。
