What is in it.
-
Built on Ubuntu 26.04 LTS
The kernel, boot loader and nearly all packages are Ubuntu’s. Nubo adds its own look, apps and helpers as ordinary packages.
-
Try it from a USB stick
Start Nubo OS without installing anything, look around, and install only if you like it. Your PC stays as it is.
-
Five years of security updates
Nubo OS 1 gets security updates to April 2031, inherited from Ubuntu 26.04 LTS.
-
Secure Boot works
The desktop image uses Ubuntu’s signed boot loader and kernel, so Secure Boot stays on.
-
A modern graphics stack
A Wayland session with fractional scaling, plus HDR and variable refresh rate on screens that support them. Hardware video decoding is on by default.
-
The Nubo glass theme
Dark by default, light supported, with Nubo icons, sounds and wallpapers.
-
Collabora Office
Collabora Office replaces LibreOffice. It opens Microsoft Office and OpenDocument files.
-
Apps from Flathub at first boot
When there is a network, first boot installs Firefox, LocalSend, Newelle, Collabora Office, Shortwave, VLC and Spotify (x86 only). Geary is the default mail app.

Nubo Search
A launcher on Super+Space. Its system-info telemetry is off.
-
Phone link and notifications
A notification center, desktop widgets and a phone link (GSConnect and scrcpy).
-
Quiet privacy defaults
Ubuntu crash reporting, news in the login message, Ubuntu Pro reminders and release-upgrade prompts are off.

Will it run on my PC?
Nubo has not published minimum RAM or disk yet. Until it does, use Ubuntu’s own figures below as a reference, not as a Nubo promise.
| Item | What Nubo can say today | Status |
|---|---|---|
| Processor | 64-bit Intel or AMD (amd64), or 64-bit Arm (arm64). The arm64 desktop image is experimental and untested on real hardware. | Confirmed |
| Base | Ubuntu 26.04 LTS. Hardware that Ubuntu 26.04 supports is the starting point. | Confirmed |
| Firmware | UEFI. Secure Boot works on the desktop image. | Confirmed |
| Network | Needed for first-boot app downloads and Nubo account setup. If there is none, it tries again at the next boot. | Confirmed |
| Install media | A USB stick, or a virtual disk image in a virtual machine. | Confirmed |
| Minimum RAM | Nubo has not published minimum RAM or disk yet. | Not published |
| Minimum disk | Nubo has not published minimum RAM or disk yet. | Not published |
| Graphics for the glass blur | Not published. | Not published |
| Hardware list | There is no list of certified hardware. | Fact |
Ubuntu reference, not a Nubo requirement: Ubuntu Desktop 26.04 lists a dual-core 2 GHz processor, 6 GB of RAM and 25 GB of disk.
What does not run.
- Adobe Creative Cloud.
- Microsoft Office desktop apps. Office files open fine in Collabora Office.

Questions
- Is Nubo OS the same as Nubo Suite?
- No. Nubo Suite is the family: Nubo OS, Nubo Email and the private apps. Nubo OS is a free operating system that you can use with or without a Nubo account.
- Is Nubo OS Ubuntu?
- It is based on Ubuntu 26.04 LTS but it is not a Canonical product. Ubuntu is a trademark of Canonical Ltd and is used here only to name the base system.
- Who makes it?
- Chandorkar Technologies.
- Is Nubo OS open source?
- Yes. The code is public at github.com/Chandorkar-Technologies/nubo-os under the GNU General Public License, version 3 or later. The Nubo name and mark are trademarks and are not covered by that license. Nubo Suite and its apps are not open source.
- Is it free?
- Yes.
- Which version is it?
- Nubo OS 1 "Flow", in beta. Server images are ready to download. The desktop is in early access.
- How long is it supported?
- Nubo OS 1 gets five years of security updates, to April 2031. There is no separate Nubo end-of-life date.
- Is it ready for my main computer?
- It is a beta. Try it from a USB stick first and keep backups of anything you care about.
- Can I try it without installing?
- Yes. Start it from a USB stick. The live session already has the Nubo packages.
- Can I keep Windows next to it?
- The installer is Ubuntu’s installer with Nubo branding, so Ubuntu’s dual-boot route applies. There is a documentation page on os.nubosuite.tech.
- Does Secure Boot work?
- Yes, on the desktop image. The boot loader and kernel are Ubuntu’s signed ones.
- Do I need internet to install?
- No, but a network helps: first boot downloads apps from Flathub and sets up a Nubo account when it can.
- Does it run on Arm?
- Packages and server images are built for arm64. The arm64 desktop image has not been tested on real hardware and is experimental.
- Can I run it in a virtual machine?
- Yes, from a virtual disk image.
- What about snaps?
- The Firefox and Thunderbird snaps are removed. Snap support stays on the desktop because the Nubo account sign-in uses it.
- What does Nubo OS send out?
- Nubo Search system-info telemetry is off and Nubo publishes no other telemetry. Some contacts with Canonical remain, such as the snap store on the desktop. They are listed in the documentation.
- Can I turn off Nubo Cumulus?
- Yes. Nubo Cumulus fetches Ubuntu packages through Nubo with Ubuntu’s servers as fallback. Create the file /etc/nubo/no-cumulus to avoid it.
- Can I sign in with a Nubo account?
- It is early access. Treat it as a preview.
- Is there a translation?
- Not yet. It is planned.
