Ubuntu 24.04 LTS - “Noble Numbat” Upgrade Guide

Ubuntu 24.04 LTS is the version of the Ubuntu operating system released in April 2024. The development code name for this version is “Noble Numbat”.

Before you begin

You can upgrade directly to Ubuntu 24.04 LTS (“Noble Numbat”) from Ubuntu 22.04 LTS (“Jammy Jellyfish”) or Ubuntu 23.10 (“Mantic Minotaur”). After Ubuntu 24.04 LTS is released, the upgrade function will not be available immediately. Upgrading from Ubuntu 23.10 will be enabled shortly after release, at which time known upgrade issues will be resolved. Upgrades from Ubuntu 22.04 LTS will not be available until Ubuntu 24.04.1 LTS is released, which is expected to be August 2024. Make sure that all updates have been applied to your current Ubuntu version before upgrading. It is recommended to read the release notes of Ubuntu 24.04 LTS before upgrading, which records notes and workarounds for known issues in this version.

If you are using Ubuntu 22.04 LTS or a version other than 23.10, see the UpgradeNotes to learn how to upgrade.
