I have not heard of any such thing and I do not know of any way to do this.

OStree is a Red Hat tool used inside the container-based Red Hat OS
products. I only know of one other company that has used OStree at
all: Endless OS, from Endless Computers.

https://endlessos.com/

This is a Debian derivative built with OStree.

It is intended to looks and work like a smartphone OS. You have no
package manager -- none at all -- and the user cannot install, remove,
or update OS components. OS updates are atomic, an entire OS image,
released periodically. Apps can only be installed as Flatpaks.

Compare to, say, Android or iOS: you have no root access to your own
OS, you don't get updates, but every few months the vendor releases a
new point-release and you install this and get a newer OS.

Your apps update separately, on top, via an app store.

This is not something you can install onto an existing OS. It
completely replaces how OSes are built and distributed.

Ubuntu has its own broadly equivalent tech: Ubuntu Core and Snappy apps.

If you want to experiment with system-image-based deployment on
Ubuntu, that's where to start.

If you want to experiment with OStree, forget Ubuntu. Try Fedora
Atomic or something..

Well no. It's a core tech from one company with an OS from a bitter
rival which doesn't include or support it, AIUI.

That is not what OStree is for.

Yes. Look elsewhere.
