我有一台配备 nVidia 卡的华硕笔记本电脑。lspci 告诉我：
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce 610M] (rev a1)
我全新安装了 Ubuntu 14.04 LTS（64 位版本）。
默认情况下，Ubuntu 14.04 使用 nouveau 驱动程序，但它们运行得不太好（光标闪烁、3D 显示缓慢等），所以我想安装专有的 nvidia 驱动程序。
我进入系统设置 > 软件和更新 > 附加驱动程序。Ubuntu 向我推荐了以下选项：
无论我尝试选择什么（Nouveau 除外），在我单击“应用更改”后，它都会恢复为 Nouveau 而没有任何额外的反馈...
因此我尝试使用 apt 手动安装驱动程序：
$ sudo apt-get install nvidia-331
Reading package lists... Done
Building dependency tree
Reading state information... Done

如果我尝试手动安装提到的软件包，我会收到此错误：
$ sudo apt install lib32gcc1 libc6-i386

我该如何修复此问题？
另外，您认为这是一个错误吗？（如果是的话，我会在 Launchpad 中提出它）
提前致谢！
答案1
好的，看来使用的更新服务器（台湾）不是最新的，导致依赖关系未得到满足和其他问题。
为了解决这个问题，我进入系统设置>软件和更新>Ubuntu 软件并选择“从主服务器下载”（之前是“从台湾服务器下载”）
现在可以安装专有驱动程序。
答案2
我也遇到了同样的错误信息。就我而言，这是因为我的 apt 缓存已损坏/过期。
因此，任何遇到同样错误的人请确保您的包定义是最新的。
apt-get update && apt-get install nvidia-331
