从Ubuntu7.04升级到7.10

1、首先 sudo sed -i 's/feisty/gutsy/' /etc/apt/sources.list

可以打开 /etc/apt/sources.list，删除或注释掉所有内容，加入下面几段（推荐使用 Ubuntu 官方源）：
deb gutsy main restricted universe multiverse
deb gutsy-security main restricted universe multiverse
deb gutsy-updates main restricted universe multiverse
deb gutsy-proposed main restricted universe multiverse
deb gutsy-backports main restricted universe multiverse
deb-src gutsy main restricted universe multiverse
deb-src gutsy-security main restricted universe multiverse
deb-src gutsy-updates main restricted universe multiverse
deb-src gutsy-proposed main restricted universe multiverse
deb-src gutsy-backports main restricted universe multiverse

2、然后 sudo apt-get update
3、接着 sudo apt-get dist-upgrade

升级是个漫长的过程.......................................................

升级完成后建议执行一下 sudo apt-get autoremove 和 sudo apt-get clean 释放空间。
