安装CUDA 10.2后未满足的依赖项

Question

我尝试使用apt安装Cuda10.2。安装过程中出现了一个错误。我能够直接安装运行.run文件从Nvidea网站。然而，当现在这样做时：

$ sudo apt upgrade

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.
 cuda-libraries-dev-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
 cuda-samples-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
 cuda-visual-tools-10-2 : Depends: libcublas-dev (>= 10.2.2.89) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

然后在做时：

$ sudo apt --fix-broken install

我得到：

The following packages were automatically installed and are no longer required:
  libllvm7 libllvm7:i386 libnvidia-common-390 libwayland-client0:i386
  libwayland-server0:i386
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
  libcublas-dev
The following NEW packages will be installed
  libcublas-dev
0 to upgrade, 1 to newly install, 0 to remove and 33 not to upgrade.
62 not fully installed or removed.

在做时：

$nvcc --version

我得到：

对如何修复破损的包裹有什么想法吗？

Answer 1

好吧，我在网上找到了一个解决方案：

1)我将素数配置文件转换为英特尔。2)将cuda.list文件移到其他地方(我已经安装了10.2版本)，3)在.bashrc中注释了一些行，其中指向cuda 10.2的路径(如果需要的话不确定) 4)重新引导$ sudo apt -fix-断开安装。

(这次成功了！)

6)在.bashrc中将素数配置文件切换回nvidia 7)未注释的行(反向步骤3) 8) $ .bashrc

而且起作用了。我现在已经安装了Cuda10.2，apt不再有中断的依赖关系。:-)
