Ubuntu Linux Unleashed 2021 Edition is filled with unique and advanced information for everyone who wants to make the most of the Ubuntu Linux operating system. This new edition has been thoroughly updated by a long-time Ubuntu user and early community leader to reflect the exciting new Ubuntu 20.04 LTS release, with a forthcoming online update mid-2021, at the halfway mark before the next LTS release comes out.

Helmke presents up-to-the-minute introductions to Ubuntu's key productivity and web development tools, programming languages, hardware support, and more. You will find new or improved coverage of the Ubuntu desktop experience, common web servers and software stacks, an introduction to containers like Docker and Kubernetes, as well as a wealth of systems administration information that is stable and valuable over many years.
