如题，有没有装过的大佬看看
网上查了一下通用驱动似乎 apt install cpus 就行了
然后我 root 运行拿到下面这个提示：（ raspbian 系统）
=======================================================

以前 x86 的 apt install 从来没出过这种问题，看不太懂
所以是没有适配版本的 cpus 还是我的某些设置有问题？
我看网上教学都是直接就装了，咋回事，很懵

看着像是不同版本软件源乱了
如果软件源乱了建议还是先看基础吧 |

似乎就是 arm 不支持， 我以前也遇到过打印机装不上，后来自己编译安装驱动后 色彩不对， 后来 x86 安装就没问题了

感谢，debug 了一下，似乎发生原因是因为使用原版源 apt upgrade，然后中途嫌太慢 ctrl+c 了，后面换成科大镜像导致的问题。 哪里的基础会讲软件源替换和冲突的原理。。不懂啊 |

@black11black 你应该是 update 一半你取消了，然后 apt 本地缓存的源信息和你实际用的源有的包版本不一致，你这时候 apt install 就会出现 apt 明明在本地缓存里找到某个包某个版本，但是去去下载的时候（实际使用的源的网址）找不到这个包了，就报错了。一般不混用源和第三方不靠谱的源很少出现版本冲突的。
