我是新用户。我很久没安装 Ubuntu 了，用 ZFS 作为根分区来试试。通过 apt 安装软件时遇到了一些问题：
user@T440S:~$ sudo apt upgrade

The following packages were automatically installed and are no longer required:

linux-modules-extra-5.3.0-42-generic
Use 'sudo apt autoremove' to remove them.

我一直无法弄清楚为什么它无法探测根池位置。 AskUbuntu 上有一些类似的问题，但没有一个与此问题完全相同。例如：
这个比较接近，但环境变量没有修复，并且由于 rpool 格式没有显示任何位置，因此在符号链接建议方面遇到了困难
ubuntu 中存在更多类似的启动板问题，但不确定如何解决：
据称这是一个修复，但不确定如何应用它。没有行尝试使用 grub_probe
我现在还不太清楚如何解决这个问题。
有任何想法吗？
