Based on the Debian distribution, Ubuntu has become a widely used operating system. Managed by Canonical Ltd., it has been around for over two decades. There is excellent support from Canonical through documentation and forums, and for a fee you can procure additional technical support. This makes the distribution a viable option for commercial operations. Ubuntu comes in many variants including: Server, Desktop, Long Term Support (LTS), and many more. It is wise to become familiar with this operating system for enthusiasts and professional alike.
