怎样优化ubuntu的源，我的太慢？

gentoofans

有什么命令吗 ？我是河南三门峡网通的，平时用apt-get时太慢，最快才十几K，现在用cn99的源。

网通应该也不会太慢啊？你应该早上早一点起来开机升级比较快，平时不会太快啊，而且这和你的带宽有一点关系，可能就是最快几十k。你可以试试下面几个源：（建议你多去Ubuntu .org.cn的论坛里去转转，那里你会知道很多你想要或是学的东西）

sudo gedit /etc/apt/sources.list在编辑器里,删除所有东西,并在加上下面的行:

deb http://archive.ubuntu.org.cn/ubuntu/ breezy main restricted universe multiverse

deb http://archive.ubuntu.org.cn/ubuntu/ breezy-security main restricted universe multiverse

deb http://archive.ubuntu.org.cn/ubuntu/ breezy-updates main restricted universe multiverse

deb http://archive.ubuntu.org.cn/ubuntu/ breezy-backports main restricted universe multiverse

deb http://archive.ubuntu.org.cn/ubuntu-cn/ breezy main restricted universe multiverse

deb http://archive.ubuntu.org.cn/backports/ breezy-extras main restricted universe multiverse

这里你也可以直接使用更快速的ubuntu.cn99.com的源（推荐）：

deb http://ubuntu.cn99.com/ubuntu/ breezy main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ breezy-updates main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ breezy-security main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu/ breezy-backports main restricted universe multiverse

deb http://ubuntu.cn99.com/ubuntu-cn/ breezy main restricted universe multiverse

deb http://ubuntu.cn99.com/backports/ breezy-extras main restricted universe multiverse

这里你还可以使用速度也非常快的的mirror.lupaworld.com的源：

deb http://mirror.lupaworld.com/ubuntu/archive/ breezy main restricted universe multiverse

deb http://mirror.lupaworld.com/ubuntu/archive/ breezy-security main restricted universe multiverse

deb http://mirror.lupaworld.com/ubuntu/archive/ breezy-updates main restricted universe multiverse

deb http://mirror.lupaworld.com/ubuntu/archive/ breezy-backports main restricted universe multiverse

deb http://mirror.lupaworld.com/ubuntu/ubuntu-cn/ breezy main restricted universe multiverse

deb http://mirror.lupaworld.com/ubuntu/backports/ breezy-extras main restricted universe multiverse保存，关闭编辑器。
祝你好运。

谢谢楼上的朋友们！我试试再说。

我用的也是河南网通，河南网通都一样，
我用这个源很快的，通常都是将近200K的速度

把dapper全改成breezy就可以了

gentoofans

兄弟怎么不早说阿，我等不及就用你那个源apt-get dist-upgrade ,结果升级成dapper,进不了X，怎么也搞不好。我欲哭无泪啊！

hermeswang

把 x-window-system-core gdm gnome gnome-core 都卸掉重新装。
先升级 kernel udev initfsram这些包
dist-grade并不是很好用的。倒不好从低到高，自己一步步来的好。

mirror.vmmatrix.net这个源不错
