正在解包 nvidia-cuda-dev (7.5.18-0ubuntu1) ...
dpkg: 处理归档 /var/cache/apt/archives/nvidia-cuda-dev_7.5.18-0ubuntu1_amd64.deb (--unpack)时出错：
 正试图覆盖 /usr/lib/x86_64-linux-gnu/stubs/libcublas.so，它同时被包含于软件包 libcublas-dev 10.2.2.89-1
dpkg-deb：错误：子进程 粘贴 被信号(断开的管道) 终止了

既然无法成功安装,尝试删除:
sudo apt remove nvidia-cuda-toolkit

最后,把 nvidia-cuda-toolkit 及那两个依赖关系破损的包都标记为彻底删除,再应用标记的更新,就成功删除了.

网上还有说处理:
dpkg error: “trying to overwrite file, which is also in…”

用
sudo dpkg -i –force-overwrite xxxxxxxxxx

或
apt-get -o Dpkg::Options::="–force-overwrite" install xxxxxxxxx

都还没试. 不知在我这里是否适用.
