Ubuntu Core has been designed to facilitate the creation, deployment, and management of secure custom images running on your own hardware.
To build an image, you need a Linux host system and one or more target systems. A target system could be a local virtual machine for testing, a single embedded system in your garage, or a fleet devices scattered across the Earth.
Pre-built test images are also available for x86-based PC-style hardware and ARM-based platforms. These are ideal for exploration and experimentation but they’re not intended for deployment or for use at scale.
We have tutorials for all approaches, with a step-by-step guide to creating your own image, plus guides on running Ubuntu Core within a virtual machine or on a variety of x86-based and ARM-based systems.
Thanks for highlighting this issue. This part of the tutorial has moved to Using Ubuntu Core, but we also updated the example to use nano-strict (as your suggested example shows). Thanks!
UC16 is supported until 2026, UC18 until 2028 (unlike for classic there is no 5y/10y separaton
of community vs commercial support here), so both are fully supported for a full 10y…
…what is not supported by snapcraft anymore is building snaps for their bases and that should be mentioned…
