Ubuntu 14.04 更换阿里云源

一、更换yum源

1、先备份

root@HDController:/home/nulige/tools# sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

root@HDController:/home/nulige/tools# cd /etc/apt/

root@HDController:/etc/apt# ll
total 44
drwxr-xr-x  6 root root  4096 Aug  1 13:53 ./
drwxr-xr-x 94 root root  4096 Aug  1 13:44 ../
drwxr-xr-x  2 root root  4096 Jul 30 16:15 apt.conf.d/
drwxr-xr-x  2 root root  4096 Apr 14  2016 preferences.d/
-rw-r--r--  1 root root  3127 Jul 29 17:50 sources.list
-rw-r--r--  1 root root     0 Jul 29 17:46 sources.list~
-rw-r--r--  1 root root  3127 Aug  1 13:52 sources.list.bak
drwxr-xr-x  2 root root  4096 Apr 14  2016 sources.list.d/
-rw-r--r--  1 root root 12255 Apr 21  2016 trusted.gpg
drwxr-xr-x  2 root root  4096 Apr 14  2016 trusted.gpg.d/

2、清空旧源文件

root@HDController:/etc/apt# >sources.list

3、编辑源文件
root@HDController:/etc/apt# vi sources.list
