Nvidia驱动程序安装未满足的依赖项[关闭]

Question

我有一台装有 1060 GPU 且安装了 Ubuntu 20.04 的笔记本电脑。我已经安装了 nvidia-driver-460 + cuda 11.2 并一直工作到今天。我今天尝试安装 ROS，在 this link 之后添加源和密钥后，它不允许我安装 ROS，说某些软件包有 unmet dependencies。之后我发出了apt autoremove 并删除了 nvidia 驱动程序 和 cuda。

我仍然无法安装 ROS，现在尝试执行apt install nvidia-driver-460 也给了我unmet dependencies。这是sudo ubuntu-drivers autoinstall 的输出，类似于apt install 命令输出

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:

E: Unable to correct problems, you have held broken packages.

这是我迄今为止尝试过但没有奏效的方法

1. apt purge *nvidia*、apt autoremove、apt autoclean 并重新安装驱动程序
2. sudo apt -f install 并重新安装驱动程序
3. sudo apt-add-repository -r ppa:graphics-drivers/ppa 并重新安装驱动程序

到目前为止，我从apt install nvidia-driver-460 得到的输出没有任何改变。非常感谢任何帮助。

我在核心 i7 机器上安装了 64 位 Ubuntu。那么为什么我在 apt install 输出中看到 i386 呢？

Answer 1

从 Software & Updates 中取消选中 cuda repo 就可以了。 （这张图片中的第5个）

Answer 2

启用restricted 存储库和安全更新：

sudo add-apt-repository restricted
echo "deb http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse" |\
sudo tee -a /etc/apt/sources.list

然后运行：

sudo apt update
sudo apt install nvidia-kernel-common-460 nvidia-driver-460
