Users are encouraged to evaluate and upgrade to our latest 24.04 LTS release via 22.04 LTS. The supported upgrade path from Ubuntu 20.04 LTS is via Ubuntu 22.04 LTS. Instructions and caveats for the upgrades may be found at:

Since its launch in October 2004, Ubuntu has become one of the most highly regarded Linux distributions with millions of users in homes, schools, businesses and governments around the world. Ubuntu is Open Source software, costs nothing to download, and users are free to customise or alter their software in order to meet their needs.

Ubuntu 25.04 (Plucky Puffin) Beta released

The Ubuntu team is pleased to announce the Beta release of the Ubuntu 25.04 Desktop, Server, and Cloud products.

Ubuntu 25.04, codenamed “Plucky Puffin”, continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs.

This Beta release includes images from not only the Ubuntu Desktop, Server, and Cloud products, but also the Kubuntu, Lubuntu, Ubuntu Budgie, UbuntuKylin, Ubuntu MATE, Ubuntu Studio, Ubuntu Unity and Xubuntu flavours.

The Beta images are known to be reasonably free of showstopper image build or installer bugs, while representing a very recent snapshot of 25.04 that should be representative of the features intended to ship with the final release expected on April 17, 2025.

Ubuntu, Ubuntu Server, Cloud Images:

Plucky Beta includes updated versions of most of our core set of packages, including a current 6.14 kernel, and much more.

To upgrade to Ubuntu 25.04 Beta from Ubuntu 24.10, follow these instructions:

https://help.ubuntu.com/community/PluckyUpgrades

The Ubuntu 25.04 Beta images can be downloaded at:

https://releases.ubuntu.com/25.04/ (Ubuntu and Ubuntu Server on x86)

This Ubuntu Server image features the next generation Subiquity server installer, bringing the comfortable live session and speedy install of the Ubuntu Desktop to server users.

Additional images can be found at the following links:

https://cloud-images.ubuntu.com/daily/server/plucky/current/ (Cloud Images)
https://cdimage.ubuntu.com/releases/24.10/beta/ (Non-x86)

As fixes will be included in new images between now and release, any daily cloud image from today or later (i.e. a serial of 20250327 or higher) should be considered a Beta image. Bugs found should be filed against the appropriate packages or, failing that, the cloud-images project in Launchpad.
