How to Upgrade Ubuntu 20.04 to 21.04
On April 22, 2021, Ubuntu 21.04 (codenamed Hirsute Hippo) was released by Canonical with security and performance improvements along with newer versions of software applications. Ubuntu 21.04 includes an SDK for Flutter application development, Microsoft SQL Server for Ubuntu, and Wayland graphics by default. Microsoft and Canonical will jointly provide support and performance tuning for Microsoft SQL Server on Ubuntu.
Although this update includes many improvements and updates, the support period is only 9 months, i.e. until January 2022. If you are looking for long-term support, then Ubuntu 20.04 LTS (codenamed Focal Fossa) is recommended, as it has 5 years of long-term support until April 2025.
