Ubuntu is a free computer operating system based on Debian GNU/Linux. Its name comes from the Zulu word "ubuntu", loosely translated as "humanity" or "A person is a person only through other people".
Ubuntu's goals include providing an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation.
Ubuntu has been rated as the most popular Linux distribution for the desktop, claiming approximately 30% of desktop Linux installations in a survey.
Ubuntu is free and open source, meaning that not only is it distributed without charge, it may also be freely improved upon. Ubuntu is sponsored by UK based company Canonical Ltd, which is owned by South African entrepreneur Mark Shuttleworth.
Instead of selling Ubuntu itself, Canonical makes money by selling paid support for Ubuntu. By keeping Ubuntu free and open Canonical is able to leverage the talents of outside developers willing to contribute rather than having to do all development within the company itself.
Kubuntu and Xubuntu are official subprojects of the Ubuntu project, aiming to bring the KDE and Xfce desktop environments, respectively, to the Ubuntu core (by default Ubuntu uses GNOME for its desktop environment). Edubuntu is an official subproject designed for school environments and should be equally suitable for children to use at home. Gobuntu was an official subproject that is aimed at adhering strictly to the Free Software Foundation's Four Freedoms. Ubuntu JeOS (pronounced "Juice") is the newest official subproject. JeOS is a concept for what an operating system should look like in the context of a virtual appliance.
Ubuntu releases new versions every six months, and supports those releases for 18 months with daily security fixes and patches to critical bugs. LTS (Long Term Support) releases, which occur every two years, are supported for three years for desktops and five years for servers. The most recent version, Ubuntu 8.04 LTS (Hardy Heron), was released on April 24, 2008, although an update, Ubuntu 8.04.1 has been released. The next version will be 8.10 (Intrepid Ibex) and is scheduled for release on 30th October 2008.
Desktop CD
The desktop CD allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. This type of CD is what most people will want to use. You will need at least 256MB of RAM to install from this CD.
There are two images available, each for a different type of computer:
- PC (Intel x86) desktop CD
- For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
- 64-bit PC (AMD64) desktop CD
- Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.
Server install CD
The server install CD allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.
There are two images available, each for a different type of computer:
- PC (Intel x86) server install CD
- For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
- 64-bit PC (AMD64) server install CD
- Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.
Alternate install CD
The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations:
- creating pre-configured OEM systems;
- setting up automated deployments;
- upgrading from older installations without network access;
- LVM and/or RAID partitioning;
- installs on systems with less than about 256MB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably).
In the event that you encounter a bug using the alternate installer, please file a bug on the debian-installer package.
There are two images available, each for a different type of computer:
- PC (Intel x86) alternate install CD
- For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
- 64-bit PC (AMD64) alternate install CD

New Features since Ubuntu 8.04
These features are showcased for your attention. Please test them and report any bugs you find on Launchpad: http://bugs.launchpad.net/ubuntu .
GNOME 2.24
Ubuntu brings you the newest GNOME 2.24 desktop environment with tons of bug-fixes and new features, some of which include:
-
Nautilus file manager has tab support (by Christian Neumair) and Eject icons for removable drives in Places sidebar (by Stefano Teso, Cosimo Cecchi, Christian Neumair, and others).
-
File Roller archive manager now supports ALZ, RZIP, CAB, TAR.7Z file types also (by Paolo Bacchilega and Changwoo Ryu).
X.Org 7.4
X.Org 7.4, the latest stable version of X.Org, is available in Intrepid. This release brings much better support for hot-pluggable input devices such as tablets, keyboards, and mice. At the same time this will allow the great majority of users to run without a /etc/X11/xorg.conf file. A new failsafe X is introduced, to give better tools for troubleshooting X startup failures.
The fglrx and two of the older nvidia binary drivers are not available for X.Org 7.4 yet, so users of these drivers will be automatically switched to the corresponding open source drivers.
Linux kernel 2.6.27
Ubuntu 8.10 Beta includes Linux kernel 2.6.27, a significant release with better hardware support and numerous bug-fixes.
Encrypted private directory
The ecryptfs-utils package was recently promoted to Ubuntu main, with support for a secret encrypted folder in your Home Folder (by Michael Halcrow, Dustin Kirkland, and Daniel Baumann).
You can help test this new feature by going to Applications → Accessories → Terminal and typing:
-
sudo aptitude install ecryptfs-utils
-
ecryptfs-setup-private
Ubuntu 8.10 Beta ships Network Manager 0.7 (by Dan Williams and others), which comes with long-expected features, such as:
- system wide settings (i.e., no need to log in in order to get a connection)
- management of 3G connections (GSM/CDMA)
- management of multiple active devices at once
- management of PPP and PPPOE connections
- management of devices with static IP configurations
- route management for devices
More information can be found on the Network Manager wiki.
DKMS (by Dell) is included in Ubuntu 8.10, allowing kernel drivers to be automatically rebuilt when new kernels are released. This makes it possible for kernel package updates to be made available immediately without waiting for rebuilds of driver packages, and without third-party driver packages becoming out of date when installing these kernel updates.
Samba 3.2
A lot of new features have been added in Samba 3.2 amongst them:
- clustered file server support
- encrypted network transport
- ipv6 support
- better integration with the latest version of Microsoft Windows™ clients and servers.
Ubuntu 8.10 Beta features a new pam-auth-update tool, which allows simple management of PAM authentication configuration for both desktops and servers (by Steve Langasek). Packages providing PAM modules will be configured automatically, and users can adjust their authentication preferences by running sudo pam-auth-update.
More information can be found in the Ubuntu wiki.
Totem BBC plugin
Ubuntu 8.10 Beta features a new plugin for the Totem movie player that fetches free digital content from the BBC. To enable it, start Totem (Applications -> Sound & Video -> Movie Player), enable the plugin (Edit -> Plugins -> BBC content viewer) and select "BBC" from the drop-down labelled "Playlist". The feed is fetched from a staging server at the moment so there may be a delay while it is downloaded.
Thanks to the BBC and Collabora for their work developing this feature.
Known Issues
There are several known bugs that users may run into with Ubuntu 8.10 Beta. We have documented them here for your convenience along with any known workarounds.
-
A problem that could result in corruption of the firmware on Intel GigE ethernet hardware has led to the disabling of the e1000e driver in the Linux kernel included in Ubuntu 8.10 Beta. Ethernet devices that use this driver cannot be used with Ubuntu 8.10 Beta; support for this hardware will be re-enabled in daily builds immediately after Beta and this issue will be resolved for the Ubuntu 8.10 final release. https://bugs.launchpad.net/bugs/263555
-
Clicking on links in GNOME programs, such as evolution, will not launch firefox automatically due to a bug in a wrapper script used by the firefox-3.0 package. As a workaround, users can launch firefox manually and copy and paste links into the location bar. https://bugs.launchpad.net/bugs/275410
-
NetworkManager 0.7 as included in Ubuntu 8.10 Beta is not compatible with static network configuration in /etc/network/interfaces. New installations are not affected by this issue because NetworkManager will manage all interfaces by default. Users upgrading from previous Ubuntu releases can work around this issue by disabling NetworkManager at startup. https://bugs.launchpad.net/bugs/256054
-
When using the Kubuntu LiveCD, the ubiquity installer hangs at the end of the installation instead of prompting you to reboot. Investigation of this issue is ongoing; as a workaround, you can safely reboot to the new system by hand. https://bugs.launchpad.net/bugs/270423
-
Installing an LTSP server fails with Ubuntu 8.10 beta because the CD is not recognized as an apt source. This will be resolved for the final release. https://bugs.launchpad.net/bugs/276349
-
The Live CD's detection of nVidia hardware incorrectly selects the 'nv' driver even for hardware not supported by that driver, preventing X from running on some systems. This issue will be fixed in daily builds immediately after Beta and will be resolved for the Ubuntu 8.10 final release. https://bugs.launchpad.net/bugs/261977
