Alternative Editions

The DVD supplied with this book also contains a number of other Ubuntu editions that are saved as ISO files—representations of an entire CD-ROM that can be easily transferred across networks and the Internet. They will take up an entire CD when copied, and can also be opened and treated like optical discs if you have the right software.

Warning

Although the installation procedures for other varieties of Ubuntu are similar, they are not identical to the directions in this chapter for installing the standard desktop edition. In fact, there are so many distros that there’s simply not enough room in this book to detail the installation process for each. Therefore, when installing an alternative edition, you should keep your eyes open, carefully read all the prompts and information provided during the process, and use your common sense when making choices and entering information.

The ISO files are located in the distros folder and are detailed in Table 2-1.

In order for you to verify that the ISO files are uncorrupted, Table 2-1 also contains the MD5 hash values for each one. These are unique strings that will be quite different if even one single byte of an ISO file is changed, compared to the original file.

To check the files using Windows, you can download a utility such as winMD5sum from http://www.nullriver.com/index/products/winmd5sum. After installation, you can compare a file’s hash value against the string value for the original ISO shown in Table 2-1. If the values are the same, you can be sure that the file is an exact copy of the original.

On Mac OS X, you can use the Disk Utility program, located in the Utilities folder, by dragging an ISO file to Disk Utility’s dock icon. Then select the ISO file and go to the Images menu, where you should select Checksum MD5.

If you wish to install any of these alternative distros, you can do so either by using a virtualization program such as VirtualBox (see the section Virtual Installation) or by burning them to CD or DVD and performing a full installation (see the section Full Installation).

If you are reading an electronic version of this book, you won’t have access to the DVD and will need to download the ISO image file that you want to install. This will also be the case if the edition you need isn’t on the DVD.

In either case, Table 2-2 lists the main URLs for downloading the various ISO distributions.

You can also access all past and present releases (since version 6.06) at http://releases.ubuntu.com.

Once you’ve downloaded the ISO file you need, you should burn it to a disc (see the following section) or perform a virtual installation from the ISO file (see the section Virtual Installation).
