Ubuntu 10.10 is the version of the Ubuntu operating system released on 10/10/2010. The common name given to this release is "Maverick Meerkat".

Before You Start

  • You can directly upgrade to Ubuntu 10.10 ("Maverick Meerkat") from Ubuntu 10.04 LTS ("Lucid Lynx") only
  • 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 10.10, which document caveats and workarounds for known issues in this version.

If you have a version of Ubuntu other than 10.04 LTS, please see UpgradeNotes for information on how to upgrade.

Upgrade from 10.04 LTS to 10.10

Network Upgrade for Ubuntu Desktops (Recommended)

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

  1. Open the Software Sources application from the System -> Administration menu

  2. Select the sub menu Updates from the Software Sources application
  3. Change the Release Upgrade drop down to "Normal Releases" and close the application
  4. Press Alt-F2 and type update-manager 

  5. Click the Check button to check for new updates.

  6. If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.

  7. A message will appear informing you of the availability of the new release.
  8. Click Upgrade.

  9. Follow the on-screen instructions.

Network Upgrade for Kubuntu Desktops (Recommended)

Direct upgrades to Kubuntu 10.10 are supported from Kubuntu 10.04 LTS only.

Upgrade Kubuntu 10.04 LTS to 10.10

Network Upgrade for Ubuntu Servers (Recommended)

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

    sudo apt-get install update-manager-core
  2. edit /etc/update-manager/release-upgrades and set Prompt=normal

  3. 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.

  1. Download the alternate installation CD from http://releases.ubuntu.com/maverick/

  2. 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 mkdir -p /media/cdrom
      sudo mount -o loop ~/Desktop/ubuntu-10.10-alternate-i386.iso /media/cdrom
  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 /media/cdrom/cdromupgrade"

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

kdesudo "sh /media/cdrom/cdromupgrade"

Upgrading from a Torrent

If you're familiar with torrents and have an ISP that doesn't limit them, you can download the upgrade much more quickly. You'll also be sharing your bandwidth with other Ubuntu users and helping to reduce the load on the servers, which is especially beneficial on release days when the server overload causes problems.

Just visit http://releases.ubuntu.com/maverick/, and download the appropriate torrent file for the alternate installation CD, found in the list towards the bottom of the page. (It will have a filename like ubuntu-10.10-alternate-i386.iso.torrent.) Load it into your BitTorrent client, and after it is done downloading the ISO, follow the alternate CD upgrade instructions.

Detailed instructions in a blog post and in a forum thread.

See the release notes.

In some cases, the installer is trying to use the network despite following the instructions above; please see: can't get lucid installer to upgrade offline, without going over the net.

If xserver-xorg-video-nouveau is installed, update-manager may fail to upgrade with a " pkgProblemResolver::Resolve generated breaks" message. To workaround this issue, remove xserver-xorg-video-nouveau and run update-manager again. If you want to use nouveau, reinstall it after the upgrade. See the relevant bug report: 10.04 -> 10.10 upgrade fails: pkgProblemResolver::Resolve generated breaks: xserver-xorg-video-v4l demoted to universe.
