Article Title: three methods to upgrade Ubuntu8.04 to 8.10. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Ubuntu 8.10 will be officially released on the last 30 days. However, as early as a few days ago, when the RC version was released, I have upgraded the original version 8.04 to 8.10. Although this upgrade does not have many major functional innovations, however, there have been many improvements in such aspects as hardware drivers and kernels. In general, the user experience is much better than the previous version.
It is estimated that after the official release of 8.10, more friends will upgrade their old versions. Here we will simply introduce the upgrade method:
I. method 1
Enter sudo update-manager-d in the command line. The system's graphical update Wizard is started, as shown in 1. This method is the easiest to use, but it is usually not too fast to get the upgrade file from its official software source by default.
Method 2
The second method is to manually upgrade the image software source. Generally, for telecom networks, you can use the lupa image source (the previously commonly used CN99 image source does not seem to be connected in the past few days ), so we need to use sudo gedit/etc/apt/sources first. list to modify the software source.
Lupa address 8.10 The software source address is:

In the CERNET environment, you can use the source of HKUST. The address is:

Deb-src http://debian.ustc.edu.cn/Ubuntu/, intrepid-security main multiverse restricted universe
Deb-src http://debian.ustc.edu.cn/Ubuntu/, intrepid-updates main multiverse restricted universe
In fact, it can be found that the software source of different versions has only changed the code of the subsequent versions. For example, the above "intrepid" is changed to "hard", which is the 8.04 source.
Then, run the following command to perform the upgrade:
Sudo apt-get update
Sudo apt-get dist-upgrade
However, we recommend that you use the preceding command to update the software package in the old version before modifying the source address of the software for upgrade to avoid dependency errors.
3. Method 3
In fact, the most thorough method is to wait until the official version is released (now you can use the RC version) for a new installation, of course, the premise is that your old version/home partition is independently mounted, otherwise, data backup and transfer will be performed across people.
In addition, do not use the Wubi installation method as much as possible. Ubuntu installed in wubi mode will be less efficient according to official statements, more importantly, it uses ubuntu as a software for windows. Although it provides a convenient user experience for windows users, the system will be damaged in case of power loss.
