从ubuntu 6.10升级到7.04

1.光盘安装
     不讲
2.从源升级
   source.list

##控制台代码
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get upgrade
有的文章如下
sudo apt-get update
sudo apt-get dist-upgrade -d
sudo update-manager -c -d
这个可能有问题.


-------------------------------------------------
出现问题了怎么办。
如果很幸运的把iso下来了，那么
把source.list备份一份，然后清空保存，执行下列命令
mount -o loop iso9660 /dev/cdrom /media/...../ubuntu.iso
sudo apt-cdrom add
然后再
sudo apt-get update
sudo apt-get dist-upgrade
就成了
----------------------------------------------------
个人还是推荐再等几天源稳定后再 更新，偶就遇到了不少麻烦
