每当我尝试安装某些东西时，都会出现以下错误：
The following packages have unmet dependencies:
cuda-samples-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed
cuda-toolkit-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed
cuda-visual-tools-8.0 : Depends: cuda-cufft-dev-8-0 but it is not going to be installed
我尝试了一下sudo apt-get -f install，它说：
The following packages were automatically installed and are no longer required:
[lots of cuda 7.5 packages and some other linux ones like linux-image-4.2.0-27-generic]
The following extra packages will be installed:
cuda-cufft-dev-8-0
The following NEW packages will be installed:
cuda-cufft-dev-8-0
Do you want to continue?
我告诉它继续，但出现此错误：
(Reading database ... 731426 files and directories currently installed.)

我尝试修复这个问题一段时间，但没能成功，所以最后我开始尝试卸载 cuda。在 /usr/local/ 中，我看到了 cuda、cuda-7.5 和 cuda-8.0（这可能不太好）。我进入所有目录寻找卸载文件（/usr/local/cuda-6.5/bin/uninstall_cuda_7.5.pl），但没有看到任何文件。
我希望升级到最新版本，但目前我也很乐意卸载它。我下一步该怎么做？
当我运行 sudo dpkg --configure -a 时我得到：

答案1
清理缓存后，你可以尝试这些，
dpkg -l | grep cuda- | awk '{print $2}' | xargs -n1 sudo dpkg --purge
df -h
sudo apt-get purge nvidia*
sudo apt-get -f install
sudo apt autoremove
希望这能帮到你。谢谢

我只需要清理缓存。最终效果如下：
sudo dpkg --configure -a
sudo apt-get clean
