卸载损坏的 cuda 安装

我下载并安装了一个使用 CUDA 10 的应用程序。当我运行它时，它显示：

./main: error while loading shared libraries: libcublas.so.10.0: cannot open shared object file: No such file or directory

文档说，它需要 CUDA 10 和 cuDNN。因此，我下载并安装了两者。（... 嗯，实际上我安装了 CUDA 10.1）。但这些都无济于事。我不确定要安装哪一个，所以我安装了开发版和运行时版。

但因为那仍然没有帮助，我安装了 nvidia-cuda-toolkit。我想那时事情真的出了问题。不可避免的事情发生了，我把它弄坏了。

我想安装另一个包：即“cuda-libraries”，但它给出了未满足的依赖关系错误，参考我之前安装的 nvidia 工具包。

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

现在，我无法返回或返回。当我尝试卸载时，它会出现错误。

此外，修复故障开关也无济于事。它尝试安装某些东西，然后再次出错。

我怎样才能拯救我的系统？例如卸载所有内容。

答案1

我遇到了基本相同的问题，但接受的答案对我的情况（Ubuntu 18.04）不起作用。我已经安装了cuda-10.1，但（如原始问题）cuda-9.1仍然存在。这个帖子很有帮助。

dpkg -l | grep -e cuda-.*9-1 | awk '{print $2}' | xargs -n1 sudo dpkg --purge --force-all
sudo apt-get remove nvidia-cuda-toolkit

这两行应该会删除 9.1（它应该会从 中消失/usr/local）。现在进行清理：

sudo apt autoremove
sudo apt update && sudo apt full-upgrade

答案2

为了一个新的开始。 sudo mv /usr/include/cublas.h /usr/include/cublas.h.bak

dpkg：处理存档 /var/cache/apt/archives/nvidia-cuda-dev_9.1.85-3ubuntu1_amd64.deb (--unpack) 时出错：尝试覆盖“/usr/include/cublas.h”，而它也位于软件包 libcublas-dev 10.2.0.168-1 中

2 个软件包包含相同的文件，并且 dpkg 在没有任何 --force 选项的情况下不会覆盖它。

sudo dpkg --configure nvidia-cuda-dev and ` sudo dpkg --configure nvidia-cuda-toolkit`

然后尝试删除违反 apt 的包。sudo dpkg -P cuda-libraries-10-0 libnvidia-common-390

下一步

sudo dpkg --configure -a && sudo apt -f install

某些软件包需要升级。但前提是您之前没有收到任何错误消息。

sudo apt update && sudo apt full-upgrade

答案3

无论是接受的答案也不是的答案user3658307为我解决了这个问题（Ubuntu 18.04.5 LTS；与问题中的而不是/usr/include/cublas.h相冲突）。相反，以下基于的解决方案libcublas-dev 10.2.2.89-110.2.0.168-1这个答案对我有用：

sudo dpkg -i --force-overwrite /var/cache/apt/archives/nvidia-cuda-dev_9.1.85-3ubuntu1_amd64.deb

执行此操作会导致出现很多dpkg: warning:消息，甚至会出现以下输出：

[...]

dpkg: error processing package nvidia-cuda-dev (--install):
 dependency problems - leaving unconfigured

[...]

但是，随后运行以下命令修复了我的机器上损坏的依赖关系：

sudo apt -f install
