shell save-logs Chapter 6. Using the Ubuntu Installer Allows the user to execute a shell from the menu, or in the second console. Provides a way for the user to record information on a hard disk, floppy disk, network, or other (removable) media when trouble is encountered, in order to accurately report installer software problems to Ubuntu developers later. In this section we will describe each installer component in detail. The components have been grouped into stages that should be recognizable for users. They are presented in the order they appear during the install. Note that not all modules will be used for every installation; which modules are actually used depends on the installation method you use and on your hardware. Let’s assume the Ubuntu Installer has booted and you are facing its first screen. At this time, the capabilities of debian-installer are still quite limited. It doesn’t know much about your hardware, preferred language, or even the task it should perform. Don’t worry. Because debian-installer is quite clever, it can automatically probe your hardware, locate the rest of its components and upgrade itself to a capable installation system. However, you still need to help debian-installer with some information it can’t determine automatically (like selecting your preferred language, keyboard layout or desired network mirror). You will notice that debian-installer performs hardware detection several times during this stage. The first time is targeted specifically at the hardware needed to load installer components (e.g. your CD-ROM or network card). As not all drivers may be available during this first run, hardware detection needs to be repeated later in the process. During hardware detection debian-installer checks if any of the drivers for the hardware de- vices in your system require firmware to be loaded. If any firmware is requested but unavailable, a dialog will be displayed that allows the missing firmware to be loaded from a removable medium. See Section 6.4 for further details. One of the first things debian-installer does, is to check available memory. If the available mem- ory is limited, this component will make some changes in the installation process which hopefully will allow you to install Ubuntu on your system. The first measure taken to reduce memory consumption by the installer is to disable translations, which means that the installation can only be done in English. Of course, you can still localize the installed system after the installation has completed. If that is not sufficient, the installer will further reduce memory consumption by loading only those components essential to complete a basic installation. This reduces the functionality of the installation system. You will be given the opportunity to load additional components manually, but you should be aware that each component you select will use additional memory and thus may cause the installation to fail. 47 6.3.1.1.
