Ubuntu7.10升级方式？

[yexin218]

我在网上看到两种不同在线升级方式：
第一种：
1.

Press Alt+F2 to run a command, or open a terminal window
2.

Run the following command:

代码： 全选

  update-manager -d

3.

Follow the on-screen instructions

第二种：

代码： 全选

sudo sed -i 's/feisty/gutsy/'  /etc/apt/sources.list
  sudo apt-get update
  sudo apt-get dist-upgrade

请问这两种方法有区别吗？另外在线升级A卡需要注意什么？
谢谢！

我用的第1种方法，先选择一个速度快的源，再升级。

我的升级的时候速度大概200KB/s ，下载了700多MB的文件，花了大概1个小时，然后安装了半小时

1.

Make sure that you have the packages "ubuntu-minimal" and "ubuntu-standard" installed, regardless of whether you're using Ubuntu, Kubuntu, Xubuntu or Edubuntu:
*

Example:

sudo apt-get install ubuntu-minimal ubuntu-standard

2.

The appropriate desktop package for your version of Ubuntu must also be installed. They are "ubuntu-desktop" for Ubuntu, "kubuntu-desktop" for Kubuntu, "xubuntu-desktop" for Xubuntu, and "edubuntu-desktop" for Edubuntu:
*

Example:

For Ubuntu

sudo apt-get install ubuntu-desktop

For Kubuntu

sudo apt-get install kubuntu-desktop

For Xubuntu

sudo apt-get install xubuntu-desktop

For Edubuntu

sudo apt-get install edubuntu-desktop

3.

Edit your /etc/apt/sources.list as root. Change every occurrence of edgy to feisty. It is also recommended that you remove or disable any extra repository that may have been added besides the Ubuntu repositories.
*

Long route: Use your preferred editor. If you have a CD-ROM line in your file, then remove it.

For Ubuntu.

gksudo gedit /etc/apt/sources.list

For Kubuntu.

kdesu kate /etc/apt/sources.list

For Xubuntu.

gksudo mousepad /etc/apt/sources.list

In any terminal program.

sudo nano /etc/apt/sources.list
sudo vi /etc/apt/sources.list

*

Shortcut:

sudo sed -e 's/\sedgy/ gusty/g' -i /etc/apt/sources.list

NOTE: This might not remove old CD-ROM lines. Manual inspection is suggested after running this command. (see Long Route)
4.

If you have the alternate install CD, you can save bandwidth by loading the CD into your CD-ROM drive and using:
*

sudo apt-cdrom add

5.

Perform the upgrade:
*

sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get dist-upgrade

OR, You can also use Aptitude:

sudo aptitude update && sudo aptitude dist-upgrade && sudo aptitude dist-upgrade

NOTE: The first run of dist-upgrade will upgrade everything except for upstart. After this a second dist-upgrade will finish the upgrade.
6.

Just to be totally sure that everything is installed properly, run these commands:
*

sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get -f install
sudo dpkg --configure -a

Running dist-upgrade again is done to ensure that no packages are left to install or upgrade. In some cases, certain packages fail to install even after running dist-upgrade the second time.
7.

Reboot in order to effect all changes. (kernel upgrades, upstart, etc...)
