當我嘗試在 22.04（系統 76）筆記型電腦上升級到最新核心映像時，從 tmp 卸載似乎是 ZFS 磁碟區的磁碟區時出現錯誤：

我確實啟用了加密，如果這很重要的話。
目前我的筆記型電腦重新啟動乾淨，沒有其他問題。我只是堅持升級到最新的圖像。
我認為 amdgpu 警告是轉移注意力，可以忽略。

我的錯誤訊息基本上與你相同。失敗的安裝部分也可以apt upgrade透過 複製到進程之外sudo update-grub。
我們認為它可能與最近安裝的 sophos 防毒軟體有關，因此透過 停用sudo systemctl stop sophos-spl.service。此後就sudo update-grub成功了。由於我們一直在嘗試其他命令來手動刪除舊的核心映像等，所以我們這樣做了sudo apt-get dist-upgrade，sudo apt --fix-broken install這讓系統回到了一個愉快的地方。
