当我尝试在我的 22.04（系统 76）笔记本电脑上升级到最新的内核映像时，我收到一个错误，从 tmp 卸载一个似乎是 ZFS 卷的卷：
$ sudo apt upgrade

如果这很重要的话，我确实启用了加密。
目前我的笔记本电脑重启正常，没有其他问题。我只是坚持升级到最新映像。
我认为 amdgpu 警告只是一种障眼法，可以忽略。

我收到的错误消息和您基本相同。安装失败的部分也可以apt upgrade通过 在该过程之外进行复制sudo update-grub。
我们猜测这可能与最近安装的 sophos 防病毒软件有关，因此通过 禁用了它sudo systemctl stop sophos-spl.service。之后sudo update-grub成功了。由于我们一直在尝试其他命令来手动删除旧内核映像等，所以我们照做了sudo apt-get dist-upgrade，sudo apt --fix-broken install系统恢复正常。
