cuda驱动安装失败

You do not appear to have libc header files installed on your system.           Please install your distribution's libc development package. 

ok,我来安装libc

 sudo apt-get install libc6-dev build-essential

失败

 libc6-dev : 依赖: libc6 (= 2.31-0ubuntu9.7) 但是 2.31-0ubuntu9.9 正要被安装
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系

ok,我来找解决方法

修改sources.list文件

sudo vim /etc/apt/sources.list

换源

#ubuntu20.04
#阿里源
