Automatic Installation

For installing on multiple computers it's possible to do fully automatic installations using the Ubuntu Installer itself.

Automatic Installation Using the Ubuntu Installer

The Ubuntu Installer supports automating installs via preconfiguration files. A preconfiguration file can be loaded from the network or from removable media, and used to fill in answers to questions asked during the installation process.

Full documentation on preseeding including a working example that you can edit is in Appendix B, Automating the installation using preseeding.

Automatic Installation Using Kickstart

The Ubuntu installer has preliminary support for automating installs using Kickstart files, as designed by Red Hat for use in their Anaconda installer. This method is not as flexible as the preconfiguration file method above, but it requires less knowledge of how the installer works.

This section documents only the basics, and differences between Anaconda and the Ubuntu installer. Refer to the Red Hat documentation for detailed instructions.

To generate a Kickstart file, install the system-config-kickstart package and run system-config-kickstart. This offers you a graphical user interface to the various options available.

Once you have a Kickstart file, you can edit it if necessary, and place it on a web, FTP, or NFS server, or copy it onto the installer's boot media. Wherever you place the file, you need to pass a parameter to the installer at boot time to tell it to use the file.

To make the installer use a Kickstart file downloaded from a web or FTP server, add ks=http://url/to/ks.cfg or ks=ftp://url/to/ks.cfg respectively to the kernel boot parameters. This requires the installer to be able to set up the network via DHCP on the first connected interface without asking any questions; you may also need to add ksdevice=eth1 or similar if the installer fails to determine the correct interface automatically.

Similarly, to make the installer use a Kickstart file on an NFS server, add ks=nfs:server:/path/to/ks.cfg to the kernel boot parameters. The method supported by Anaconda of adding a plain "ks" boot parameter to work out the location of the Kickstart file from a DHCP response is not yet supported by the Ubuntu installer.

To place a Kickstart file on a CD, you would need to remaster the ISO image to include your Kickstart file, and add ks=cdrom:/path/to/ks.cfg to the kernel boot parameters. See the manual page for mkisofs for details. Alternatively, put the Kickstart file on a floppy, and add ks=floppy:/path/to/ks.cfg to the kernel boot parameters. ... Read more »

Preparing Files for TFTP Net Booting

If your machine is connected to a local area network, you may be able to boot it over the network from another machine, using TFTP. If you intend to boot the installation system from another machine, the boot files will need to be placed in specific locations on that machine, and the machine configured to support booting of your specific machine.

You need to set up a TFTP server, and for many machines a DHCP server, or BOOTP server.

BOOTP is an IP protocol that informs a computer of its IP address and where on the network to obtain a boot image. The DHCP (Dynamic Host Configuration Protocol) is a more flexible, backwards-compatible extension of BOOTP. Some systems can only be configured via DHCP.

The Trivial File Transfer Protocol (TFTP) is used to serve the boot image to the client. Theoretically, any server, on any platform, which implements these protocols, may be used. In the examples in this section, we shall provide commands for SunOS 4.x, SunOS 5.x (a.k.a. Solaris), and GNU/Linux.

[Note]

For an Ubuntu or Debian GNU/Linux server we recommend tftpd-hpa. It's written by the same author as the syslinux bootloader and is therefore least likely to cause issues. A good alternative is atftpd.

Setting up a DHCP server

One free software DHCP server is ISC dhcpd. For Ubuntu, the dhcp3-server package is recommended. Here is a sample configuration file for it (see /etc/dhcp3/dhcpd.conf):

option domain-name "example.com";
option domain-name-servers ns1.example.com;
option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 7200;
server-name "servername";

subnet 192.168.1.0 netmask 255.255.255.0 {
 range 192.168.1.200 192.168.1.253;
 option routers 192.168.1.1;
}

host clientname {
 filename "/tftpboot.img";
 server-name "servername";
 next-server servername;
 hardware ethernet 01:23:45:67:89:AB;
 fixed-address 192.168.1.90;
}

Preparing Files for Hard Disk Booting

The installer may be booted using boot files placed on an existing hard drive partition, either launched from another operating system or by invoking a boot loader directly from the BIOS.

A full, "pure network installation can be achieved using this technique. This avoids all hassles of removable media, like finding and burning CD images or struggling with too numerous and unreliable floppy disks.

The installer cannot boot from files on an NTFS file system.

Hard disk installer booting using LILO or GRUB

This section explains how to add to or even replace an existing linux installation using either LILO or GRUB.

At boot time, both bootloaders support loading in memory not only the kernel, but also a disk image. This RAM disk can be used as the root file-system by the kernel.

Copy the following files from the Ubuntu archives to a convenient location on your hard drive, for instance to /boot/newinstall/.

  • vmlinuz (kernel binary)

  • initrd.gz (ramdisk image)

Finally, to configure the bootloader proceed to the section called "Booting from Linux Using LILO or GRUB.

Preparing Files for USB Memory Stick Booting

There are two installation methods possible when booting from USB stick. The first is to install completely from the network. The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror. This second method is the more common.

For the first installation method you'll need to download an installer image from the netboot directory (at the location mentioned in the section called "Where to Find Installation Images”) and use the "flexible way explained below to copy the files to the USB stick.

Installation images for the second installation method can be found in the hd-media directory and either the "easy way or the "flexible way can be used to copy the image to the USB stick. For this installation method you will also need to download a CD image. The installation image and the CD image must be based on the same release of debian-installer. If they do not match you are likely to get errors[6] during the installation.

To prepare the USB stick, you will need a system where GNU/Linux is already running and where USB is supported. With current GNU/Linux systems the USB stick should be automatically recognized when you insert it. If it is not you should check that the usb-storage kernel module is loaded. When the USB stick is inserted, it will be mapped to a device named /dev/sdX, where the "X is a letter in the range a-z. You should be able to see to which device the USB stick was mapped by running the command dmesg after inserting it. To write to your stick, you may have to turn off its write protection switch.

Downloading Files from Ubuntu Mirrors

To find the nearest (and thus probably the fastest) mirror, see the list of Ubuntu mirrors.

When downloading files from an Ubuntu mirror using FTP, be sure to download the files in binary mode, not text or automatic mode.

Where to Find Installation Images

The installation images are located on each Ubuntu mirror in the directory ubuntu/dists/maverick/main/installer-i386/current/images/ — the MANIFEST lists each image and its purpose.

Official Ubuntu CD-ROMs

By far the easiest way to install Ubuntu is from an Official Ubuntu CD-ROM. You may download the CD-ROM image from an Ubuntu mirror and make your own CD, if you have a fast network connection and a CD burner. If you have an Ubuntu CD and CDs are bootable on your machine, you can skip right to Chapter 5, Booting the Installation System; much effort has been expended to ensure the files most people need are there on the CD.

If your machine doesn't support CD booting, but you do have a CD, you can use an alternative strategy such as hard disk, usb stick, net boot, or manually loading the kernel from the CD to initially boot the system installer. The files you need for booting by another means are also on the CD; the Ubuntu network archive and CD folder organization are identical. So when archive file paths are given below for particular files you need for booting, look for those files in the same directories and subdirectories on your CD.

Once the installer is booted, it will be able to obtain all the other files it needs from the CD.

If you don't have a CD, then you will need to download the installer system files and place them on the hard disk or usb stick or a connected computer so they can be used to boot the installer.

Pre-Installation Hardware and Operating System Setup

This section will walk you through pre-installation hardware setup, if any, that you will need to do prior to installing Ubuntu. Generally, this involves checking and possibly changing firmware settings for your system. The "firmware is the core software used by the hardware; it is most critically invoked during the bootstrap process (after power-up). Known hardware issues affecting the reliability of Ubuntu on your system are also highlighted.

Invoking the BIOS Set-Up Menu

BIOS provides the basic functions needed to boot your machine to allow your operating system to access your hardware. Your system probably provides a BIOS setup menu, which is used to configure the BIOS. Before installing, you must ensure that your BIOS is set up correctly; not doing so can lead to intermittent crashes or an inability to install Ubuntu.

The rest of this section is lifted from the http://www.faqs.org/faqs/pc-hardware-faq/part1/, answering the question, "How do I enter the CMOS configuration menu?. How you access the BIOS (or "CMOS) configuration menu depends on who wrote your BIOS software:

AMI BIOS

Delete key during the POST (power on self test)

Award BIOS

Ctrl+Alt+Esc, or Delete key during the POST

DTK BIOS

Esc key during the POST

IBM PS/2 BIOS

Ctrl+Alt+Insert after Ctrl+Alt+Delete

Phoenix BIOS

Ctrl+Alt+Esc or Ctrl+Alt+S or F1

Pre-Partitioning for Multi-Boot Systems

Partitioning your disk simply refers to the act of breaking up your disk into sections. Each section is then independent of the others.javascript:// It's roughly equivalent to putting up walls inside a house; if you add furniture to one room it doesn't affect any other room.

If you already have an operating system on your system (Windows 9x, Windows NT/2000/XP, OS/2, MacOS, Solaris, FreeBSD, …) and want to stick Linux on the same disk, you will need to repartition the disk. Ubuntu requires its own hard disk partitions. It cannot be installed on Windows or MacOS partitions. It may be able to share some partitions with other Linux systems, but that's not covered here. At the very least you will need a dedicated partition for the Ubuntu root.

You can find information about your current partition setup by using a partitioning tool for your current operating system, such as fdisk or PartitionMagic. Partitioning tools always provide a way to show existing partitions without making changes.

In general, changing a partition with a file system already on it will destroy any information there. Thus you should always make backups before doing any repartitioning. Using the analogy of the house, you would probably want to move all the furniture out of the way before moving a wall or you risk destroying it.

If your computer has more than one hard disk, you may want to dedicate one of the hard disks completely to Ubuntu. If so, you don't need to partition that disk before booting the installation system; the installer's included partitioning program can handle the job nicely.

If your machine has only one hard disk, and you would like to completely replace the current operating system with Ubuntu, you also can wait to partition as part of the installation process (the section called "Partitioning and Mount Point Selection”), after you have booted the installation system. However this only works if you plan to boot the installer system from tapes, CD-ROM or files on a connected machine. Consider: if you boot from files placed on the hard disk, and then partition that same hard disk within the installation system, thus erasing the boot files, you'd better hope the installation is successful the first time around. At the least in this case, you should have some alternate means of reviving your machine like the original system's installation tapes or CDs.

If your machine already has multiple partitions, and enough space can be provided by deleting and replacing one or more of them, then you too can wait and use the Ubuntu installer's partitioning program. You should still read through the material below, because there may be special circumstances like the order of the existing partitions within the partition map, that force you to partition before installing anyway.

If your machine has a FAT or NTFS filesystem, as used by DOS and Windows, you can wait and use Ubuntu installer's partitioning program to resize the filesystem.

Meeting Minimum Hardware Requirements

Once you have gathered information about your computer's hardware, check that your hardware will let you do the type of installation that you want to do.

Depending on your needs, you might manage with less than some of the recommended hardware listed in the table below. However, most users risk being frustrated if they ignore these suggestions.

A Pentium 4, 1GHz system is the minimum recommended for a desktop system.

Table 3.2. Recommended Minimum System Requirements

Install Type RAM (minimal) RAM (recommended) Hard Drive
No desktop 64 megabytes 256 megabytes 1 gigabyte
With Desktop 64 megabytes 512 megabytes 5 gigabytes

The actual minimum memory requirements are a lot less then the numbers listed in this table. Depending on the architecture, it is possible to install Ubuntu with as little as 20MB (for s390) to 48MB (for i386 and amd64). The same goes for the disk space requirements, especially if you pick and choose which applications to install; see the section called "Disk Space Needed” for additional information on disk space requirements.

Information You Will Need

Documentation

Installation Manual

The document you are now reading, which is the official version of the Installation Guide for the maverick release of Ubuntu.

Hardware documentation

Often contains useful information on configuring or using your hardware.

Finding Sources of Hardware Information

In many cases, the installer will be able to automatically detect your hardware. But to be prepared, we do recommend familiarizing yourself with your hardware before the install.

Hardware information can be gathered from:

  • The manuals that come with each piece of hardware.

  • The BIOS setup screens of your computer. You can view these screens when you start your computer by pressing a combination of keys. Check your manual for the combination. Often, it is the Delete key.

  • The cases and boxes for each piece of hardware.

  • The System window in the Windows Control Panel.

  • System commands or tools in another operating system, including file manager displays. This source is especially useful for information about RAM and hard drive memory.

  • Your system administrator or Internet Service Provider. These sources can tell you the settings you need to set up your networking and e-mail.

Back Up Your Existing Data!

Before you start, make sure to back up every file that is now on your system. If this is the first time a non-native operating system has been installed on your computer, it's quite likely you will need to re-partition your disk to make room for Ubuntu. Anytime you partition your disk, you run a risk of losing everything on the disk, no matter what program you use to do it. The programs used in installation are quite reliable and most have seen years of use; but they are also quite powerful and a false move can cost you. Even after backing up, be careful and think about your answers and actions. Two minutes of thinking can save hours of unnecessary work.

If you are creating a multi-boot system, make sure that you have the distribution media of any other present operating systems on hand. Especially if you repartition your boot drive, you might find that you have to reinstall your operating system's boot loader, or in many cases the whole operating system itself and all files on the affected partitions.

Overview of the Installation Process

First, just a note about re-installations. With Ubuntu, a circumstance that will require a complete re-installation of your system is very rare; perhaps mechanical failure of the hard disk would be the most common case.

Many common operating systems may require a complete installation to be performed when critical failures take place or for upgrades to new OS versions. Even if a completely new installation isn't required, often the programs you use must be re-installed to operate properly in the new OS.

Under Ubuntu, it is much more likely that your OS can be repaired rather than replaced if things go wrong. Upgrades never require a wholesale installation; you can always upgrade in-place. And the programs are almost always compatible with successive OS releases. If a new program version requires newer supporting software, the Ubuntu packaging system ensures that all the necessary software is automatically identified and installed. The point is, much effort has been put into avoiding the need for re-installation, so think of it as your very last option. The installer is not designed to re-install over an existing system.

Here's a road map for the steps you will take during the installation process.

  1. Back up any existing data or documents on the hard disk where you plan to install.

  2. Gather information about your computer and any needed documentation, before starting the installation.

  3. Create partitionable space for Ubuntu on your hard disk.

  4. Locate and/or download the installer software and any specialized driver files your machine requires (except Ubuntu CD users).

  5. Set up boot tapes/floppies/USB sticks, or place boot files (most Ubuntu CD users can boot from one of the CDs).

  6. Boot the installation system.

  7. Select the installation language.

  8. Activate the ethernet network connection, if available.

  9. Create and mount the partitions on which Ubuntu will be installed.

  10. Watch the automatic download/install/setup of the base system.

  11. Install a boot loader which can start up Ubuntu and/or your existing system.

  12. Load the newly installed system for the first time.

Memory and Disk Space Requirements

You must have at least 44MB of memory and 500MB of hard disk space to perform a normal installation. Note that these are fairly minimal numbers. For more realistic figures, see the section called "Meeting Minimum Hardware Requirements”.

Installation on systems with less memory or disk space available may be possible but is only advised for experienced users.

Installation Media

This section will help you determine which different media types you can use to install Ubuntu. For example, if you have a floppy disk drive on your machine, it can be used to install Ubuntu. There is a whole chapter devoted to media, Chapter 4, Obtaining System Installation Media, which lists the advantages and disadvantages of each media type. You may want to refer back to this page once you reach that section.

CD-ROM/DVD-ROM

[Note]

Whenever you see "CD-ROM in this manual, it applies to both CD-ROMs and DVD-ROMs, because both technologies are really the same from the operating system's point of view, except for some very old nonstandard CD-ROM drives which are neither SCSI nor IDE/ATAPI.

CD-ROM based installation is supported for some architectures. On machines which support bootable CD-ROMs, you should be able to do a completely floppy-less installation. Even if your system doesn't support booting from a CD-ROM, you can use the CD-ROM in conjunction with the other techniques to install your system, once you've booted up by other means; see Chapter 5, Booting the Installation System.

SCSI, SATA and IDE/ATAPI CD-ROMs are supported. The Linux CD-ROM HOWTO contains in-depth information on using CD-ROMs with Linux.

USB CD-ROM drives are also supported, as are FireWire devices that are supported by the ohci1394 and sbp2 drivers.

Hard Disk

Booting the installation system directly from a hard disk is another option for many architectures. This will require some other operating system to load the installer onto the hard disk.

USB Memory Stick

Many Ubuntu boxes need their floppy and/or CD-ROM drives only for setting up the system and for rescue purposes. If you operate some servers, you will probably already have thought about omitting those drives and using an USB memory stick for installing and (when necessary) for recovering the system. This is also useful for small systems which have no room for unnecessary drives.

Purchasing Hardware Specifically for GNU/Linux

There are several vendors, who ship systems with Debian or other distributions of GNU/Linux pre-installed. You might pay more for the privilege, but it does buy a level of peace of mind, since you can be sure that the hardware is well-supported by GNU/Linux.

If you do have to buy a machine with Windows bundled, carefully read the software license that comes with Windows; you may be able to reject the license and obtain a rebate from your vendor. Searching the Internet for "windows refund may get you some useful information to help with that.

Whether or not you are purchasing a system with Linux bundled, or even a used system, it is still important to check that your hardware is supported by the Linux kernel. Check if your hardware is listed in the references found above. Let your salesperson (if any) know that you're shopping for a Linux system. Support Linux-friendly hardware vendors.

Avoid Proprietary or Closed Hardware

Some hardware manufacturers simply won't tell us how to write drivers for their hardware. Others won't allow us access to the documentation without a non-disclosure agreement that would prevent us from releasing the Linux source code.

Since we haven't been granted access to the documentation on these devices, they simply won't work under Linux. You can help by asking the manufacturers of such hardware to release the documentation. If enough people ask, they will realize that the free software community is an important market.

Devices Requiring Firmware

Besides the availability of a device driver, some hardware also requires so-called firmware or microcode to be loaded into the device before it can become operational. This is most common for network interface cards (especially wireless NICs), but for example some USB devices and even some hard disk controllers also require firmware.

In most cases firmware is non-free according to the criteria used by the Debian GNU/Linux project and thus cannot be included in the main distribution or in the installation system. If the device driver itself is included in the distribution and if Debian GNU/Linux legally can distribute the firmware, it will often be available as a separate package from the non-free section of the archive.

However, this does not mean that such hardware cannot be used during an installation. Starting with Debian GNU/Linux 5.0, debian-installer supports loading firmware files or packages containing firmware from a removable medium, such as a floppy disk or USB stick. See the section called "Loading Missing Firmware” for detailed information on how to load firmware files or packages during the installation.

Supported Hardware

Ubuntu does not impose hardware requirements beyond the requirements of the Linux kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux kernel, libc, gcc, etc. have been ported, and for which an Ubuntu port exists, can run Ubuntu.

Rather than attempting to describe all the different hardware configurations which are supported for Intel x86, this section contains general information and pointers to where additional information can be found.

Supported Architectures

Ubuntu 10.10 supports three major architectures and several variations of each architecture known as "flavors. Three other architectures (HP PA-RISC, Intel ia64, and IBM/Motorola PowerPC) have unofficial ports.

What is GNU/Linux?


Linux is an operating system: a series of programs that let you interact with your computer and run other programs.

An operating system consists of various fundamental programs which are needed by your computer so that it can communicate and receive instructions from users; read and write data to hard disks, tapes, and printers; control the use of memory; and run other software. The most important part of an operating system is the kernel. In a GNU/Linux system, Linux is the kernel component. The rest of the system consists of other programs, many of which were written by or for the GNU Project. Because the Linux kernel alone does not form a working operating system, we prefer to use the term "GNU/Linux to refer to systems that many people casually refer to as "Linux.

Linux is modelled on the Unix operating system. From the start, Linux was designed to be a multi-tasking, multi-user system. These facts are enough to make Linux different from other well-known operating systems. However, Linux is even more different than you might imagine. In contrast to other operating systems, nobody owns Linux. Much of its development is done by unpaid volunteers.

Development of what later became GNU/Linux began in 1984, when the Free Software Foundation began development of a free Unix-like operating system called GNU.

The GNU Project has developed a comprehensive set of free software tools for use with Unix™ and Unix-like operating systems such as Linux. These tools enable users to perform tasks ranging from the mundane (such as copying or removing files from the system) to the arcane (such as writing and compiling programs or doing sophisticated editing in a variety of document formats).

While many groups and individuals have contributed to Linux, the largest single contributor is still the Free Software Foundation, which created not only most of the tools used in Linux, but also the philosophy and the community that made Linux possible.

What is Debian?


Debian is an all-volunteer organization dedicated to developing free software and promoting the ideals of the Free Software community. The Debian Project began in 1993, when Ian Murdock issued an open invitation to software developers to contribute to a complete and coherent software distribution based on the relatively new Linux kernel. That relatively small band of dedicated enthusiasts, originally funded by the Free Software Foundation and influenced by the GNU philosophy, has grown over the years into an organization of around 890 Debian Developers.

Debian Developers are involved in a variety of activities, including Web and FTP site administration, graphic design, legal analysis of software licenses, writing documentation, and, of course, maintaining software packages.

In the interest of communicating our philosophy and attracting developers who believe in the principles that Debian stands for, the Debian Project has published a number of documents that outline our values and serve as guides to what it means to be a Debian Developer:

  • The Debian Social Contract is a statement of Debian's commitments to the Free Software Community. Anyone who agrees to abide to the Social Contract may become a maintainer. Any maintainer can introduce new software into Debian — provided that the software meets our criteria for being free, and the package follows our quality standards.

  • The Debian Free Software Guidelines are a clear and concise statement of Debian's criteria for free software. The DFSG is a very influential document in the Free Software Movement, and was the foundation of the The Open Source Definition.

  • The Debian Policy Manual is an extensive specification of the Debian Project's standards of quality.

Debian developers are also involved in a number of other projects; some specific to Debian, others involving some or all of the Linux community. Some examples include:

  • The Linux Standard Base (LSB) is a project aimed at standardizing the basic GNU/Linux system, which will enable third-party software and hardware developers to easily design programs and device drivers for Linux-in-general, rather than for a specific GNU/Linux distribution.

  • The Filesystem Hierarchy Standard (FHS) is an effort to standardize the layout of the Linux file system. The FHS will allow software developers to concentrate their efforts on designing programs, without having to worry about how the package will be installed in different GNU/Linux distributions.

  • Debian Jr. is an internal project, aimed at making sure Debian has something to offer to our youngest users.

For more general information about Debian, see the Debian FAQ.

What is Ubuntu?


Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit.

  • Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition, we make our very best work available to everyone on the same Free terms.

  • Ubuntu includes the very best in translations and accessibility infrastructure that the Free Software community has to offer, to make Ubuntu usable by as many people as possible.
