更换ubuntu apt-get 源
为了优化ubuntu软件安装/更新速度,我测试了国内几家apt源的速度,发现北京交大的apt源速度相对最快,然后可以通过以下步骤更新ubuntu源
1) 备份默认的apt源
1 $ cd /etc/apt 2 $ sudo cp sources.list sources.list.backup
2) 编辑
$ sudo gedit sources.list
复制粘贴以下列表:
1 deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse 2 deb http://archive.ubuntu.com/ubuntu/ raring-security main restricted universe multiverse 3 deb http://archive.ubuntu.com/ubuntu/ raring-updates main restricted universe multiverse 4 deb http://archive.ubuntu.com/ubuntu/ raring-proposed main restricted universe multiverse 5 deb http://archive.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse 6 deb-src http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse 7 deb-src http://archive.ubuntu.com/ubuntu/ raring-security main restricted universe multiverse 8 deb-src http://archive.ubuntu.com/ubuntu/ raring-updates main restricted universe multiverse 9 deb-src http://archive.ubuntu.com/ubuntu/ raring-proposed main restricted universe multiverse 10 deb-src http://archive.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse
3) 注意,每次修改完apt源,一定要执行一下更新
$ sudo apt-get update
大概花了几分钟,更新完成之后,就可以使用apt来安装应用程序了。
