Ubuntu Cinnamon

Ubuntu Cinnamon is a community-driven, free and open-source Linux distribution based on Ubuntu, using the Cinnamon desktop environment in place of Ubuntu's GNOME Shell. The first release was 19.10 'Eoan Ermine' on December 4, 2019, and is the first official distribution to use Ubuntu with the Cinnamon desktop. Ubuntu Cinnamon Remix is also used synonymously to reference the project.

History

The Cinnamon environment was developed by the Linux Mint team in 2011 and was first used as the default desktop environment in Linux Mint 13. Ideas to combine Ubuntu and Cinnamon were not new, and had been floated around several times before the project. However, the idea was never developed significantly.
In 2019, user ItzSwirlz posted on Ubuntu Discourse requesting info on a Cinnamon Ubuntu Flavor. He stepped up to build the project, and the first release was released later that year on SourceForge.

Flavor Status

As early as 2020, Peisach expressed interest in attaining flavor status for Ubuntu Cinnamon Remix.
In 2022, Peisach emailed the Ubuntu Technical Board requesting official flavor status. In the Ubuntu Technical Board meeting over IRC on March 28, 2023, Ubuntu Cinnamon was officially deemed a flavor by Ubuntu.
