無法安裝 nvidia-driver-455（從 450 版本升級）

我有一個基於 Linux Mint 20 Cinnamon Nvidia (GTX 1060) 的系統，當我注意到最新的 Nvidia 驅動程序已經出局時，我想立即安裝它們。

但是，我似乎無法安裝它：

apt-get --dry-run install nvidia-driver-455

拋出以下內容：

我沒有任何持有的包裹，也沒有任何剩餘配置。

目前，我在核心 5.4.0-54-generic 上執行**版本 450，沒有任何問題。**那麼，我現在該怎麼辦？如何調查這個？

問題已解決，由於某種原因，仍然安裝了以前安裝版本的元包：nvidia-driver-440. 已經在 3 台筆記型電腦上複製，有問題的包保持不變，並阻止 Nvidia 更新。

在整體更新作業系統後，我重新啟動並發出：

apt-get purge nvidia-driver-440

結果：

現在上面的試執行似乎沒問題。以 root 身份安裝：

apt-get --install-recommends install nvidia-driver-455

進展順利，我的系統現在啟動沒有任何問題。
