如何从光盘升级UBUNTU

njkzkj

因为网络问题，我下载 了一张UBUNTU的7.04盘，想升级家里的机器
怎么做呢？
因为不想重安装了
我只有DESKTOP版的，没下ALTERNATIVE版的
Upgrading using the alternate CD/DVD

Use this method if the system being upgraded is not connected to the Internet.

   1.

      Download and burn the alternate installation CD
   2.

      Insert it into your CD-ROM drive
   3.

      A dialog will be displayed offering you the opportunity to upgrade using that CD
   4.

      Follow the on-screen instructions

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu "sh /cdrom/cdromupgrade"

网络方式升级啊。
或者下一个alternative cd的ISO，不需要刻盘，直接挂载升级安装。
