Luks 从 17.10 更新到 18.04 后坏了

debugcn 发表于 Dev

可组合

我有一台包含所有更新的17.10笔记本电脑。它正在使用全盘加密

我今天刚更新到 18.04。一切顺利，最后要求我重启，我也是。

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.

还以为是内核版本的问题。用以前的内核测试过，没有帮助。

我也用 18.04 和 17.10 的实时 USB 记忆棒进行了测试，但没有更多的运气：

按照此线程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。

我当然对密码有信心。

有关如何进行的任何提示？

您应该尝试回答这个问题：使用全盘加密的 Ubuntu - 升级到 18.04 后密码错误

它对我有用。
