Upgrade to Ubuntu 810


1. Before You Start
2. Network Upgrade for Ubuntu Desktops (Recommended)
1. Network Upgrade for Kubuntu Desktops (Recommended)
2. Network Upgrade for Ubuntu Servers (Recommended)
3. Upgrading Using the Alternate CD/DVD

This document provides instructions and notes on upgrading to Ubuntu 8.10, released on the 30th of October 2008. Separate instructions exist for upgrading to 8.04 LTS from previous versions.
Before You Start

By default Ubuntu 8.04 LTS will not offer a upgrade to 8.10. This is because the 8.04 LTS version is a long term support release and 8.10 is a regular release. Upgrades from 8.04 LTS to 8.10 are fully supported, of course, and easy to enable.


You can directly upgrade to Ubuntu 8.10 from Ubuntu 8.04 LTS (see UpgradeNotes).

The upgrade will not be presented by default because 8.10 is not a Long Term Support (LTS) release.
* Be sure that you have all updates applied to Ubuntu 8.04 LTS before you upgrade.

Before upgrading it is recommended that you read the release notes for Ubuntu 8.10, which document caveats and workarounds for known issues in this version.

If you have a version of Ubuntu which was released before Ubuntu 8.04 LTS, please see Installation/UpgradeFromOldVersion for information on how to upgrade.
Network Upgrade for Ubuntu Desktops (Recommended)

You can easily upgrade over the network with the following procedure.

1. Start System/Administration/Software Sources

Upgrading to Ubuntu 8.10

2. click on the "Updates" tab and change "Show new distribution release" to "Normal releases"

3. Start System/Administration/Update Manager


Click the Check button to check for new updates.

If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.
6. A message will appear informing you of the availability of the new release.


Click Upgrade.
8. Follow the on-screen instructions.

Network Upgrade for Kubuntu Desktops (Recommended)

To upgrade from 8.04 to Kubuntu 8.10, over the Internet, use the following procedure.

For a full graphical presentation of these steps, please review IntrepidUpgrades/Kubuntu.


Open the Run Command dialog by pressing Alt+F2. Type kdesu "adept_manager --dist-upgrade-devel" in the command box and press the OK button.

The Version Upgrade button will appear. Click it.
3. Follow the prompts

Network Upgrade for Ubuntu Servers (Recommended)


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:



Launch the upgrade tool:

sudo do-release-upgrade

4. Follow the on-screen instructions.

Upgrading Using the Alternate CD/DVD

Use this method if the system being upgraded is not connected to the Internet.


Download the alternate installation CD

Burn the ISO to a CD and insert it into the CD-ROM drive of the computer to be upgraded.

If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:

sudo mount -o loop ~/Desktop/ubuntu-8.10-alternate-i386.iso /media/cdrom0

3. A dialog will be displayed offering you the opportunity to upgrade using that CD.
4. Follow the on-screen instructions.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu "sh /cdrom/cdromupgrade"

Or in Kubuntu run the following command using Alt+F2:

kdesudo "sh /cdrom/cdromupgrade"
