自帶的 軟件包源 不好用，卡頓嚴重，准備替換它：
方式一：deepin linux 如何更新或者更換軟件源（注意：好像不起作用）
方式二：【推薦】利用 阿里雲 提供的鏡像快速更換本地的 yum 源 （CentOS/Ubuntu/Deepin 等系統都被支持），點擊右邊的“help”，會告訴你如何替換為“阿里雲源”
方式三：替換為 “中國科學技術大學”源
sudo vim /etc/apt/sources.list
把其中的 “http://packages.deepin.com”替換為“http://mirrors.ustc.edu.cn”
最后，更新源
sudo apt-get update
個人電腦 /etc/apt/sources.list 文件的最終效果
“中國科學技術大學”源 和 阿里雲源 混合用
