Ubuntu 8.04 LTS is the upcoming version of the Ubuntu operating system. The common name given to this release from the time of its early development was “Hardy Heron”.

Before you start

• You can directly upgrade to Ubuntu 8.04 LTS (”Hardy Heron”) from Ubuntu 7.10 (”Gutsy Gibbon”) or from Ubuntu 6.06 LTS (”Dapper Drake”). This page continues 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 8.04 LTS, which document caveats and workarounds for known issues in this version.

Note: If you have a version of Ubuntu other than 6.06 LTS or 7.10, please see Installation/UpgradeFromOldVersion for information on how to upgrade.
