Cuda 有未满足的依赖项。无法安装

我一直在尝试安装 cuda，但我无论如何也想不出这个问题 :(。这是我一直遇到的错误，我想不出这台机器上会出现什么问题。这是 Ubuntu Server 的全新安装（uname -aLinux marte 4.18.0-11-generic #12-Ubuntu SMP Tue Oct 23 19:22:37 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux运行 Cosmic）

% sudo apt-get install cuda

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 cuda : Depends: cuda-10-0 (>= 10.0.130) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

其他一些可能有用的信息吗？

我尝试查找任何损坏的包裹

编辑：尝试手动安装未满足的依赖项，我遇到了以下问题

                          bumblebee but it is not going to be installed

有没有人有什么建议？

答案1

问题是 ubuntu 不知道在哪里找到这些包。在终端中输入以下代码：

add-apt-repository ppa:graphics-drivers/ppa

答案2

提供 xorg-vide-abi-* 的软件包是 xserver-xorg-core(2:1.19.6-ubuntu4.2)，但保留的软件包是 xserver-xorg-core(2:1.20*)，并且不再提供必要的 xerver-xorg-core 软件包

因此，降级该软件包有效，并sudo apt-mark hold xserver-xorg-core在升级时忽略该软件包（）即可。
