自带的 软件包源 不好用，卡顿严重，准备替换它：

方式一：deepin linux 如何更新或者更换软件源（注意：好像不起作用）

方式二：【推荐】利用 阿里云 提供的镜像快速更换本地的 yum 源 （CentOS/Ubuntu/Deepin 等系统都被支持），点击右边的“help”，会告诉你如何替换为“阿里云源”

方式三：替换为 “中国科学技术大学”源

sudo vim /etc/apt/sources.list

把其中的 “http://packages.deepin.com”替换为“http://mirrors.ustc.edu.cn”

最后，更新源

sudo apt-get update

个人电脑 /etc/apt/sources.list 文件的最终效果

“中国科学技术大学”源 和 阿里云源 混合用
