This article mainly explains "what are the differences between Fedora 21 and Fedora 22". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the differences between Fedora 21 and Fedora 22"?

Update all packages of Fedora 21 to the latest status first

The first step is to update all packages for Fedora 21 to the latest state. Use a sudo dnf update command to:

Sudo dnf update

In fact, dnf can be used to manage software packages in Fedora 21, but dnf and yum coexist in 21, while yum is abandoned completely in Fedora 22. The dnf command and the yum command are almost completely compatible, making it easy to switch.

Install the fedup package

The tool for this upgrade is fedup. The package needs to be installed on its own, with the following commands:

Sudo dnf install fedup

Upgrade the system

The third step is to upgrade the system. Use the following command directly:

Sudo fedup-network 22

Solve the problem of errors in the process of system upgrade

I thought everything would go well in the upgrade process, but there was an accident in the upgrade process. The error message is also clear, referring to the python language's error in parsing ascii characters. Using the error message to search on the Internet, it is found that this is a problem written by python script, which can be solved by loading the utf-8 module. It shows that there is still a little flaw in the fedup package, which I have already submitted. But it's impossible for me to modify the fedup script myself. How did I solve this problem? It is very simple to change the system language to English. Change it to Chinese after the upgrade is completed. In other words, the Chinese system will make mistakes in the upgrade process, while the English system will not.

Restart the system

Restart the system and select the first item in the startup screen of Grub, as shown below:

Then wait for the upgrade to be completed, which will take some time.

Changes in the new system

The upgrade process is smooth and the upgraded system is stable. The difference between the upgraded system and the newly installed system is to maintain the user's configuration as much as possible. For example, my upgraded system does not even change the wallpaper, while the newly installed system has another set of wallpaper. However, Fedora 22 still has a little change compared with Fedora 21. The window theme is gone, and there is no way to set the window theme in gnome-tweak-tool. You can only set the GTK+ theme. So I said goodbye to clearlooks and chose the default theme. The default theme of Fedora 22 is really much prettier than the previous version.

The above is the method of upgrading Fedora 21 to Fedora 22. Users of the Fedora 21 version can manually upgrade to Fedora 22 if they are not prompted to update the notification automatically.
