Ubuntu 24.04 LTS is the version of the Ubuntu operating system released in April 2024. The development codename given to this release is "Noble Numbat".

Before You Start

You can directly upgrade to Ubuntu 24.04 LTS ("Noble Numbat") from either Ubuntu 22.04 LTS ("Jammy Jellyfish") or Ubuntu 23.10 ("Mantic Minotaur").
Upgrades will not be available immediately following the release of Ubuntu 24.04 LTS. Upgrades from Ubuntu 23.10 will be enabled shortly after the release, once any known upgrade issues are resolved. Upgrades from Ubuntu 22.04 LTS are not enabled until the release of Ubuntu 24.04.1 LTS. This is currently scheduled for August 2024.
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 24.04 LTS, which document caveats and workarounds for known issues in this version.

If you have a version of Ubuntu other than 22.04 LTS or 23.10, please see UpgradeNotes for information on how to upgrade.
