dpkg：处理存档 /var/cache/apt/archives/cuda-cublas-9-1_9.1.85.3-1_amd64.deb (--unpack) 时出错

当我运行 sudo apt-get -f install 时，它显示 dpkg：错误处理。请查看下面的完整日志并建议如何解决此问题。我应该删除旧版本吗？

答案1

您收到的错误是：

dpkg: error processing archive /var/cache/apt/archives/cuda-cublas-9-1_9.1.85.3-1_amd64.deb (--unpack):
 trying to overwrite '/usr/local/cuda-9.1/lib64', which is also in package cuda-cudart-9-1 9.1.85-1

这 ”试图覆盖“错误意味着您的系统中存在冲突的软件包。您可以尝试覆盖该软件包（可能有点冒险）

sudo dpkg -i --force-overwrite /var/cache/apt/archives/cuda-cublas-9-1_9.1.85.3-1_amd64.deb You need to remove that package

如果这不能解决问题，您可以删除该包并重新安装

sudo dpkg -P cuda-cublas
