Ubuntu has long been recognized as one of the most popular and widely used Linux distributions among desktop users.

However, it has experienced fluctuations in its popularity, particularly during the period when it introduced significant changes to its desktop experience with the user interface.

This gives users more options for desktop environments, all with official support. The support period can differ (usually 3 years for non-LTS and 5 years for LTS versions), but releasing them together makes it easier for both individuals and companies to choose.
