Moving to the Next Ubuntu Release

So now your system is up-to-date, but Ubuntu doesn't like to let the grass grow. One of the original goals for Ubuntu was to have frequent releases, and with only one notable exception (the 6.06 LTS release, which was delayed by two months), there have been six months between each release since 4.10. This book has been revised for the latest version—7.04, also known as Feisty Fawn—but another one will be along soon. Should you move to it, and if so, how do you do it? Well, to answer the first question you have to understand that unlike the Long Term Support (LTS) versions of Ubuntu, the normal versions are supported for eighteen months and are superseded by a new version every six months. By comparison, the LTS versions (currently only 6.06 carries this classification) are supported for three years on desktop computers, and five years on servers. Essentially, if you are running the LTS version—which came with the first edition of this book—you are probably not that interested in moving to the latest and greatest, at least until the next LTS version comes out. However, if you're running the version supplied with this book, you will more than likely move to the next version when it's released, which is currently scheduled for October 2007.

Doing the Actual Upgrade

Since Ubuntu 6.06 was released, upgrading is far easier as there is a graphical tool that tells you when a new version of Ubuntu is available, and it walks you through the upgrade process. Note that if you already know or want to learn the manual method, that is fine, too. Both means will achieve the same result.

When a new release is available, the update manager will tell you that a new version is available. Click on the Upgrade button to start the process. You will first be shown the release notes, which mention new features or any outstanding bugs. After you click on the Upgrade button on this screen, the necessary changes to your software repositories are made, and then the program will download and install the new distribution. You may be prompted if you have changed any configuration files. After the actual installation is complete, you will be told which packages are no longer supported (have moved to universe). Last, all you need to do is restart your computer when prompted, and you will shortly be enjoying the new release.

You can also initiate an upgrade simply by inserting a CD that contains a newer version of Ubuntu than the one you are currently running. Follow the prompts for an upgrade experience similar to using the update manager.
