Ubuntu 21.04 (Hirsute Hippo) Final Beta released

21.04, codenamed “Hirsute Hippo”, 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, 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 21.04 that should be representative of the features intended to ship with the final release expected on April 22nd, 2021.

Ubuntu, Ubuntu Server, Cloud Images:
Hirsute Beta includes updated versions of most of our core set of packages, including a current 5.11 kernel, and much more. To upgrade to Ubuntu 21.04 Beta from Ubuntu 20.10, follow these instructions:


The Ubuntu 21.04 Beta images can be downloaded at:

http://releases.ubuntu.com/21.04/ (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.

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 20210401 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.
