抱歉，截图不过能反映出我的问题。
Ubuntu 19.10 加密 LVM2 设置
我已遵循我能找到的所有指南。
检查 rootdelay、/proc/modules 是否存在，是否按照此处所述执行了 cryptsetup luksOpen 等 -更新 initramfs删除了我所有的 nvidia 驱动程序。删除了专门用于存储数据的驱动器上损坏的 lvm raid0 设置。
结果没什么区别，依然无法开机。

下一步该怎么解决这个问题？
更新 1：
在将 crypttab 文件更改为此之后，我再次尝试了上面链接的“更新 initramfs”文章中的步骤
sdc3_crypt /dev/sdc3 none luks,discard
同时更改 /etc/cryptsetup-initramfs/conf-hook 中的 CRYPTSETUP=y
然后在最后一步得到这个'update-initramfs -c -k all'
cryptsetup: ERROR: Couldn't fnd sysfs directory for 253:1
Google 搜索返回了 7 个帖子，但没有一个能解释错误的原因。但删除了 CRYPTSETUP=y 并重试。这完成了该过程，但重启时出现同样的错误
