通用方法
- 換國內(nèi)源斗忌，最直接的就是上阿里、中科大的鏡像官網(wǎng)兔院。
-
根據(jù)選擇自己的Linux發(fā)行版姿鸿，點幫助help就有詳細了谆吴，復制到sources.list，更新下源就好了苛预。

Ubuntu換國內(nèi)源
Xubunut句狼、Kubuntu都是ubuntu發(fā)行版，只是桌面環(huán)境不同热某，換源也是一樣鲜锚。
-
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak備份原來的sorce文件 -
sudo gedit /etc/apt/sources.list修改sources.list文件
gedit是ubuntu自帶的圖像界面編輯器突诬，xubuntu苫拍、kubuntu自帶的不是gedit芜繁，Kubuntu自帶kate。你也可以用vi/vim去編輯绒极。
sudo vim /etc/apt/sources.list
- 添加阿里骏令、中科大鏡像源
