ubuntu

Ubuntu is a Debian-based Linux operating system that runs from the desktop to the cloud, to all your internet connected things. It is the world's most popular operating system across public clouds and OpenStack clouds. It is the number one platform for containers; from Docker to Kubernetes to LXD, Ubuntu can run your containers at scale. Fast, secure and simple, Ubuntu powers millions of PCs worldwide.

Development of Ubuntu is led by Canonical Ltd. Canonical generates revenue through the sale of technical support and other services related to Ubuntu. The Ubuntu project is publicly committed to the principles of open-source software development; people are encouraged to use free software, study how it works, improve upon it, and distribute it.
