We hope you enjoy Ubuntu 6.06.
What's new
Ubuntu is released regularly and predictably. Since our October 2005 release (Ubuntu 5.10), we've made a lot of improvements to give you the best Linux experience possible. Here's what's new with Ubuntu 6.06:
On the Desktop
- GNOME 2.14.1
New tools to easy search your files (Deskbar)
OpenOffice.org 2.0.2
- X.org 7 with wider hardware support
Editable GNOME menus (Alacarte Menu Editor)
- Applications are now linked into the Launchpad infrastructure (new entries on the Help menus for translation and support)
Graphical shut down process with progress bar (USplash)
New documentation (Ubuntu Desktop Guide, Ubuntu Server Guide, Ubuntu Packaging Guide)
- Firefox 1.5.0.3
- New Human GNOME Desktop Theme
- Improved and simplified application menu structure
Graphical .deb package installer (GDebi)
On the Server
- New kernels targeted at server platforms. The server kernels are tuned differently than the desktop kernels (providing better performance for server applications). The lowend server kernel is generic, and should work on the same equipment that the desktop kernel runs on. The highend server kernel is geared towards systems with greater than 8 CPU's (ES7000/Summit/BIGSMP).
- Support for the full Redhat Cluster Suite
Hardware Support Improvements
Installation
- A new installer on the Live CD/Desktop Installation CD which is now the prefered method of installing Ubuntu. This CD image will fit on standard 650MB CDs.
- The traditional text-mode Debian Installer (d-i) based installer is still also available for special installation scenarios. This CD image requires a 700MB CD.
- A new dedicated official Ubuntu Server installation CD is also available for use on server. This CD is a minimal server CD and is only ~300MB in size.
"Under the hood"
As always, Ubuntu includes the very best of the 100% free/libre application software world, and each new release incorporates countless new features and bugfixes from the global development community.
- The shell path for the system is now set in one place, /etc/environment, for ease of administration. In the past, each shell, display manager, login program, etc. needed to be configured separately.
sudo's handling of environment variables has been made robust against security vulnerabilities: all environment variables but TERM, PATH, LOGNAME, USER, and locale settings are now cleaned for users with restricted sudo privileges. This might break local scripts which rely on the old behavior.
Downloading and Installing
Ubuntu 6.06 supports three (3) major architectures: Intel x86, AMD64, and PowerPC. 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.

128 megabytes |
2 gigabytes |

64 megabytes |
500 megabytes |
Here are some common Ubuntu 6.06 system configurations. Once again, the size of the installation will greatly depend on the software you install during setup. For most users, the default applications are suitable enough for general use.
Desktop
A standard desktop box, including the X Window System, full desktop environment, sound, office suite, email clients, etc. You'll need about 2 gigabytes of hard drive space using the standard desktop task.
Server
This is a small server profile, which provides a common base for all sorts of server applications. It's minimal and designed to have the desired services added on top, such as file/print services, web hosting, email hosting, etc. For these services at least 500MB of disk space will suffice, but consider adding more space depending on the services you'd like to host with your server.
Remember that these sizes don't include all the other materials which are usually to be found, such as user files, mail, and data. It is always best to be generous when considering the space for your own files and data.
Downloading Ubuntu 6.06
You can download Ubuntu 6.06 from the following mirrors located worldwide:

You can also download all architecture types of Ubuntu 6.06 using BitTorrent and Jigdo.
Getting Help and Technical Support

Once you have an active internet connection, from an open application, just click on Help → Get Help Online and you'll be directed to an online webpage that gives you help and support options for the application.
