In late April, shortly after the release of Ubuntu 22.04, System76 He launched Pop! _OS 22.04. That version of the operating system is based on Jammy Jellyfish and GNOME 42, but it still includes all its own customizations that have made some users prefer this distribution over others. The operating system was originally designed for System76 computers, but the version for any laptop or desktop computer has long existed.
Now, three months after the launch for "normal" computers, the company announced that also there is an image for the Raspberry Pi 4. If we go to the download page of Pop!_OS 22.04, we can see that there is one that says "22.04 (RAS PI 4)", which shows two differences with respect to the other images: first, it is not an LTS version, for which is not supported for as long as the desktop version; second, it's for the Raspberry Pi 4. And, if we read a little further down, we can see that the company has given this version a special name for the raspberry board.
Pop!_Pi, Pop!_OS for the Raspberry Pi
The name given to this operating system is Pop!_Pi, and is only supported for the Raspberry Pi 4 with 2GB of RAM or more. It can also be used on the Raspberry Pi 400, since what it has inside is mostly an RPi4.
It is important to mention that what is available is a «Technical Preview», that is, a preview version. As such, it is intended for developers or users who want to test this version of the operating system on their Raspberry Pi, but not for those who want to work with something 100% reliable.
The desktop version arrived at the end of April with news such as PipeWire as the default audio processing system, support for scheduling updates, improvements in light and dark themes and Linux 5.16, and not the 5.15 that Ubuntu 22.04 uses. The image can be found at official project page.
