我想从我的系统中完全删除 cuda 10.2，其中还有一些其他 cuda 版本。文档说
sudo apt-get --purge remove <package_name>
我应该用 替换 package_name 吗cuda*10-2*？
在其他帖子中使用 apt-get 删除软件包和依赖项，我发现我也应该这样做
sudo apt-get purge $(apt-cache depends <PACKAGENAME> | awk '{ print $2 }' | tr '\n' ' ')
sudo apt-get autoremove
sudo apt-get update
sudo apt-get check
sudo apt-get -f install
sudo apt-get autoclean
但也许更好的解决方案是sudo aptitude remove cuda*10-2*？
