Server releases of Ubuntu Version details and compatibility information.
The versions differ mainly in stability and updates. 21.04 offers more recent features and security fixes, while 20.04.3 LTS is a stable release ideal for beginners setting up a web server on a Raspberry Pi 4. Choose based on your need for updates versus reliability.
LTS stands for long-term support, indicating Ubuntu provides five years of updates for the current release. Others receive only eight to nine months.
21.04 will come with a slightly updated software package, but chances are you won’t need it. The added stability and ease of setup for a long time will be far more beneficial. For servers, LTS is the best choice. On desktops, it comes down to how important you are about newer releases and needing frequent distro updates every few months.
