The system is simple but It is very stable, command line operation can facilitate the management of systems and applications, and is supported by helpful documentation and community.

9. The Ubuntu system has a beautiful user interface, a complete package management system, powerful software source support, and a rich technical community. Ubuntu's support for computer hardware is better than centos and Debian, and it has strong compatibility. Ubuntu has many applications, but for a server operating system, it does not need too many applications. What is needed is a system that is stable, easy to operate, and simple to maintain.
