These images are a great way to quickly get started with Ubuntu Core on a Raspberry Pi, for example, or to explore Ubuntu Core’s features and evaluate its potential. Canonical produces official images for the following platforms:

Ubuntu Core 18 (UC18) images are available from http://cdimage.ubuntu.com/ubuntu-core/18/stable/current/.

Ubuntu Core 20 (UC20) images are available from http://cdimage.ubuntu.com/ubuntu-core/20/stable/current/.

UC20 is built on the foundation of Ubuntu 20.04 LTS (Focal Fossa), is currently under active development. See Ubuntu Core 20 for more details.

Ubuntu community members also work with, and produce, images for other platforms and CPUs. Refer to these individual projects for more information on what other unofficial images might work for your use cases.
