尝试删除包会抱怨未满足的依赖项

Kar*_*rus 7 package-management apt cuda 18.04

在 Ubuntu 18.04 上，我在安装 CUDA 时遇到了一些问题，所以我想卸载 CUDA 并从头开始。

所以，我尝试了以下方法：

sudo apt remove cuda

但这随后打印出以下内容：

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-10-1 : Depends: libcublas-dev (>= 10.2.1.243) but it is not going to be installed
 cuda-samples-10-1 : Depends: libcublas-dev (>= 10.2.1.243) but it is not going to be installed
 cuda-visual-tools-10-1 : Depends: libcublas-dev (>= 10.2.1.243) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

我对此感到非常困惑。它似乎在告诉我cuda-libraries-dev-10-1，cuda-samples-10-1, 和cuda-visual-tools-10-1都依赖于libcublas-dev，至少版本为 10.2.1.243。然后说这个版本的libcublas-dev不会被安装。但我正在尝试卸载CUDA，而不是安装它。因此，当我尝试删除这些软件包时，为什么我的系统要关心 CUDA 附带的某些软件包具有未满足的依赖项？

我可以理解，如果我尝试安装cuda-libraries-dev-10-1、cuda-samples-10-1、或cuda-visual-tools-10-1，那么这条消息就有意义。但是如果我试图删除这些，谁在乎它们是否有未满足的依赖项？

按照建议，我也跑了：

apt --fix-broken install

然后打印出来：

正如评论中所建议的那样，我然后尝试运行：

sudo apt full-upgrade

这打印出以下内容：

这与我运行时的打印结果完全相同sudo apt remove cuda。

正如评论中所建议的，我跑了grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d。这给出了以下输出：

我有同样的问题。这救了我（用你的包版本替换）：

sudo dpkg -i --force-overwrite /var/cache/apt/archives/libcublas-dev_10.2.1.243-1_amd64.deb

进而：

sudo apt --fix-broken install

如果这有效，请尝试再次清除 cuda

Unpacking libcublas-dev (10.2.1.243-1) ... dpkg: error processing archive /var/cuda-repo-10-1-local-10.1.243-418.87.00/./libcublas-dev_10.2.1.243-1_amd64.deb (--unpack): trying to overwrite '/usr/lib/x86_64-linux-gnu/libcublas_static.a', which is also in package nvidia-cuda-dev 9.1.85-3ubuntu1

让我们稍微解释一下这个错误：您有两个不兼容的包，因为每个包都尝试提供相同的文件。这两个包是libcublas-dev（来自 CUDA）和nvidia-cuda-dev（来自 Ubuntu）。

他们都尝试提供的文件是/usr/lib/x86_64-linux-gnu/libcublas_static.a

您有多种选择。

您可以放弃 CUDA、卸载 CUDA 软件包并删除 CUDA 存储库。
您可以卸载 NVIDIA 软件包。不要删除 Ubuntu 存储库。
您可以使用 dpkg 的--force-overwrite标志来使两个不兼容的包一起工作。那么你不需要卸载或删除任何东西。
```
sudo apt install --force-overwrite libcublas-dev
```

使用--force时应小心。它可能会导致未来的升级、删除或其他包操作出现问题。请务必在您自己的注释中记录您需要用来--force-overwrite一起安装 CUDA 和 NVIDIA 软件包的信息。
