![grub 上的 pbkdf2 密码在我的 Ubuntu 22.04 Vm 上不起作用](https://linux22.com/image/788473/grub%20%E4%B8%8A%E7%9A%84%20pbkdf2%20%E5%AF%86%E7%A0%81%E5%9C%A8%E6%88%91%E7%9A%84%20Ubuntu%2022.04%20Vm%20%E4%B8%8A%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
我在 VirtualBox VM 上安装了 Ubuntu 22.04.3 LTS。安装完成后,我按照此处的说明配置了 pbkdf2https://help.ubuntu.com/community/Grub2/密码。我在运行 update-grub 后还验证了 grub.cfg,它看起来是正确的。无论如何,当系统启动时,它不会要求我输入任何用户/密码,即使我不使用“--unrestricted”参数。在这里我粘贴了我的 /boot/grub/grub.cfg:

我认为您没有设置超级用户。
检查拼写,set superuser=foo
vsset superusers=foo
