This document provides instructions and notes on upgrading to Ubuntu 10.04 LTS (code name "Lucid Lynx"), the most recent release of Ubuntu, released on the 29th of April 2010.

Before You Start

You can directly upgrade to Ubuntu 10.04 LTS ("Lucid Lynx") from Ubuntu 9.10 ("Karmic Koala") or from Ubuntu 8.04 LTS ("Hardy Heron"). This page contains instructions for both. (see UpgradeNotes)
Be sure that you have all updates applied to your current version of Ubuntu before you upgrade.

Before upgrading it is recommended that you read the release notes for Ubuntu 10.04 LTS, which document caveats and workarounds for known issues in this version.

If you have a version of Ubuntu other than 8.04 LTS or 9.10, please see UpgradeNotes for information on how to upgrade.

Network Upgrade for Kubuntu Desktops

Because Kubuntu 8.04 was not an LTS release and has passed its end of life, direct upgrades to Kubuntu 10.04 LTS from Kubuntu 8.04 are not supported. Please follow the directions for upgrading Kubuntu 8.04 to 9.10 first, then follow the directions above for upgrades from Kubuntu 9.10.

Network Upgrade for Ubuntu Servers (Recommended)

Ensure you're up to date with latest release:

    sudo apt-get update

    sudo apt-get upgrade


Install update-manager-core if it is not already installed:

    sudo apt-get install update-manager-core


edit /etc/update-manager/release-upgrades and set Prompt=lts

Note: The minumum contents of /etc/update-manager/release-upgrades should be

[DEFAULT]
Prompt=lts


Launch the upgrade tool:

    sudo do-release-upgrade


Follow the on-screen instructions.

At the end of the upgrade process you will be required to restart the server in order to boot into the new kernel. If you do not have access to the console of the system you are upgrading, you may need to edit /boot/grub/menu.lst and change the default boot kernel to the newly installed 10.04 kernel. If this step is not performed your server may attempt to boot into the 8.04 LTS kernel and will hang.
