In which distribution groups can Ubuntu be classified?

Ubuntu can be classified into several groups of distributions:

1. Debian-based — Ubuntu is based on Debian and inherits its package management system (APT, .deb).
2. Desktop and Server — there are versions of Ubuntu for desktop PCs with a graphical interface and minimal server builds.
3. LTS (Long Term Support) and regular releases — LTS versions are supported longer (usually 5 years), regular ones — about 9 months.
4. Cloud and IoT — special editions of Ubuntu for cloud platforms (e.g., Ubuntu Cloud) and Internet of Things devices.

Thus, Ubuntu can be viewed as a distribution from the Debian family with various options for different tasks and support periods.
