安装时出现CUDA错误，有助于卸载
我使用blender工作，我将Ubuntu升级到18.04。 升级后，我安装了CUDA工具包，但现在我收到有关依赖项的错误，我想删除我安装的所有内容。 我该怎么做？

CUDA想要使用的驱动程序（nvidia-390）与您安装的驱动程序之间存在冲突。 我有同样的问题： "which is also in package nvidia-340..."对我来说，这是通过首先清除旧的nvidia驱动程序解决的
sudo dpkg -P nvidia-340
只有这样
sudo apt --fix-broken install
工作。 你可以通过清除一切
sudo apt purge nvidia*
sudo apt purge cuda*
您可以继续获取更新的nvidia驱动程序
sudo apt install nvidia-390 nvidia-390-dev
安装nvidia-384驱动程序也应该可以工作，但我不确定。
