What you're missing out if you don't try Ubuntu Core 22
Ubuntu Core, the Ubuntu flavour optimised for IoT and edge devices, has a new version available. With a 2-year release cadence, every new release is both an exciting and challenging milestone. Ubuntu Core is based on Ubuntu. It is open source, long-term supported (LTS), binary compatible and offers a unified developer experience. It allows developers and makers to build composable and software-defined appliances built from immutable snap container images.
