Nubo OS
Nubo OS is a free, open source operating system built on Ubuntu 26.04 LTS, in beta, for desktops and servers. Start here for the facts.
Nubo OS is a free operating system for desktops and servers made by Chandorkar Technologies. It is built on Ubuntu 26.04 LTS, so the kernel, boot loader and nearly all packages are Ubuntu’s, with Nubo’s look, apps and helpers added as ordinary packages. Nubo OS 1 “Flow” is in beta. Server images can be downloaded today; the desktop is early access on request.
Nubo OS is a separate product from Nubo Suite. It is open source, and the code is at github.com/Chandorkar-Technologies/nubo-os.
