Ubuntu 6.06 LTS Release Notes

Ubuntu is a Linux distribution for your desktop or server, with a fast and easy install, regular releases, a tight selection of excellent applications installed by default, and almost any other software you can imagine available through the network. Ubuntu 6.06 LTS (Long Term Support) will be supported with security updates for 5 years on the server and 3 years on the desktop after its release, and professional technical support is available from many companies around the world.

These Release Notes cover new features in Ubuntu 6.06 LTS, download and installation notes, known issues, and frequently asked questions. Please read these notes before, during, and after installation and configuration of Ubuntu 6.06 LTS, and before reporting bugs in Launchpad. We hope you enjoy Ubuntu.

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 LTS:

On the Desktop CD

  • A new, very fast, graphical installer based on the Live CD
  • Faster system startup and login
  • Simplified menu organization
  • Graphical shutdown process
  • Easy access to power management settings with GNOME Power Manager
  • Improved support for video playback
  • Optional NetworkManager for convenient roaming between different

    • wireless and wired networks
  • GNOME 2.14.1, OpenOffice.org 2.0.2, X.org 7.0

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).
  • There are both low-end, and "big iron" server kernels. The low-end
    • 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 CPUs (ES7000 / Summit / BIGSMP).
  • Turn-key LAMP installation for this common deployment scenario
  • Improved support for clusters and SANs
  • Numerous thin client enhancements, including faster client startup,
    • graphical boot process, reduced memory requirements, and sound device support


  • Automatic setup of non-Latin input methods
  • Menu item translations included in language packs, for faster
    • integration of new and updated translations provided through Rosetta

Installation and Upgrades

  • Ubuntu can now be installed to USB devices, such as removable
    • hard drives and flash memory, using the text-mode installer
  • A new upgrade tool is available, for simple, clean and reliable
    • upgrades from one Ubuntu release to the next, starting with Ubuntu 5.10
  • The alternate installer now runs in a single stage, rebooting
    • straight into the complete system. This makes it faster, simpler, and more reliable.

"Under the hood"

  • GCC 4.0.3
  • glibc 2.3.6
  • Linux
  • New live CD infrastructure for improved performance, usability and
    • space-efficiency
  • Greatly improved infrastructure for automatic hardware detection and activation
  • The system PATH is now set in exactly one place, /etc/environment, for
    • convenient administration

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.

Downloading and Installing

Ubuntu 6.06 LTS 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. These notes are guides. For step by step upgrade instructions please see DapperUpgrades.

Table 1 Recommended Minimum Requirements

Install Type


Hard Drive Space


256 megabytes

3 gigabytes


64 megabytes

500 megabytes

Here are some common Ubuntu 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.


A standard desktop box, including a full desktop environment, sound, office suite, email clients, etc. You'll need about 3 gigabytes of hard drive space.


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.

Known Issues

  • A number of problems have been reported with the installer on the Desktop CD; the list of known issues in Ubiquity outlines some of these that can easily be avoided or worked around. Some of these will be corrected in later updates. In the meantime, if you cannot work around an installer problem with the Desktop CD, the alternate install CD remains available.

  • Server images for the SPARC architecture are undergoing final quality assurance and testing; release images will be published as soon as certifications on T1000 and T2000 are complete.
  • redhat-cluster-suite fails to install properly due to changed error reporting from ccs_test. A workaround is to install ccs first, provide a valid configuration for it, and install the rest of the suite later. See /usr/share/doc/gfs-tools/min-gfs.txt in the gfs-tools package for details. Updated packages are available via dapper-updates.

  • Upgrades from Ubuntu 5.10 on certain Dell desktop models may hang while upgrading a legacy support package for the PCMCIA subsystem. An update has been published in the dapper-updates repository to correct this problem.

  • Systems that have been upgraded from Ubuntu 5.04 (or earlier) may have to manually delete linux-image-2.6.10 packages before the upgrade.

    • The bug referenced (47537) doesn't appear to have anything to do with the linux-image package, but instead deals with problems installing additional languages. In addition, I couldn't find any bug that made reference to install problems due to old linux-image packages having previously been installed. Can anyone shed some more light on this issue?

  • If you want to use the packages from an alternate install CD when doing a upgrade, please add the CD to the system with synaptic and start update-manager. It will open a initial dialog and complain about packages it can't upgrade. This is a bug and can be ignored.

  • If you upgrade (whatever method) and have the nvidia-glx and nvidia-settings packages installed, please remove nvidia-settings, otherwise nvidia-glx will be removed on upgrade. The settings utility is now provided by the nvidia-glx package.

  • Areca Raid controllers on AMD64 (ARC-1110, 1220, and perhaps others) has file file corruption issues (see Bug #45679). Fixed in Feisty. If require LTS then use Hardy.

Getting Help and Technical Support

Ubuntu 6.06 LTS gives users an easy way to get help in most applications installed by default. 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.

Technical Support for Ubuntu is available from a variety of sources: from the community, from Canonical Ltd, from recognized organizations, and from developers directly through open web forums, mailing lists and IRC channels:

If you have a question, or if you think you may have found a bug but aren't sure, first try asking on the #ubuntu IRC channel on Freenode, on the Ubuntu Users mailing list, or on the Ubuntu forums:
