我现在在 18.04，即将升级到 20.04。我的包管理器为我提供了部分升级和 dist 升级作为选项。我认为最好先运行部分升级并尝试在升级到 20.04 之前解决任何未解决的问题。这似乎已经破坏了我的系统。重新启动后，它只是挂起并且永远不会启动（我将其放置超过 24 小时，并且它从未从仅显示 /dev/sda1 干净的消息的黑白 TTY 中移动）。
我能够重新启动并选择以前的内核版本（5.4.0-51-generic），我的系统也启动了，但使用的是 nouveau 驱动程序，分辨率很荒谬。不幸的是，显示选项没有提供任何更改它的选项，所以我尝试安装 nvidia 专有驱动程序（同样——它们以前已安装）。我仍然可以使用旧内核启动，但我似乎无法修复损坏的软件包。例如：
$ sudo apt install nvidia-driver-455

You might want to run 'apt --fix-broken install' to correct these.

我如何在这里恢复运行？我可以在 18.04 上修复这里的问题，还是直接使用 20.04 USB 密钥启动并告诉它升级我现有的安装？我试过跑步apt autoclean，apt clean但那些也无济于事。
