If we take stability as a parameter, is it safe to match them like this?
- Fedora --> Ubuntu
- CentOS Stream --> Ubuntu LTS
- RHEL --> Debian
I know that CentOS stream is more kind of a rolling release but… feels like an LTS distro in practice… or it is just me?
Edit: adding some context. I am planning to setup a dev machine that I will connect to remotely and would like to babysit very little while having stable and fresh packages. In the Ubuntu world we would go to an LTS release but on the RPM/Dnf world is there any other distro apart from CentOS Stream? And also is CentOS Stream comparable to an LTS release at all considering that they do not have release number?
- RHEL is more akin to Ubuntu LTS with a Canonical support contract.
- CentOS Stream is more like openSUSE Tumbleweed. I’m not aware of any mainstream apt-based distros that have that kind of rolling release cycle.
- Fedora is like Ubuntu.
But it’s not really a 1:1 comparison, since they all have different ideologies when it comes to package management and update cycles.
Opensure Tumbleweed is more like Fedora Rawhide, they get the absolute bleeding Edge. CentOS stream is downstream of Fedora, so you get less newer packages
I disagree, since both Stream and Tumbleweed are rolling releases with solid bases. openSUSE rigorously tests packages before deploying to the stable branch.
Ultimately, there’s not going to be a perfect analog between all of them, because like I said, they all have different ideologies and packaging goals.
RHEL --> Debian in the sense that RHEL is a root distro from which the others spring. But there the similarities very much end.
Ubuntu LTS is not newer than Debian.
CentOS Stream is also very old for some reason, they are CI/CD and get more updates, but it is just a step before RHEL.
Fedora really has no middleground which I find unperfect.
Also dont forget OpenSUSE, the free Enterprise distros, OpenEuler, Mandriva and more.
What’s your goal? Is it safe to match is a very open ended question.
Take RHEL, it’s meant to be a paid distro for enterprise, something Debian isn’t. But you could draw similarities too.
What’s are you trying to learn?
Based on your new context in your edits, you should look at Aurora or Bluefin, which is both stable and has access to whatever is in DNF.
IIRC, within RHEL it goes fedora (next major) -> centos stream (next minor) -> RHEL (current major.minor).
With Debian and its derivatives (e.g Ubuntu) this means that Debian-unstable corresponds to fedora, Debian-testing corresponds to CentOS stream and Debian-stable corresponds to RHEL. (Roughly of course).
Ubuntu is based off of some flavor of Debian and is therefore downstream of it: Debian (unstable I think) -> Ubuntu -> Ubuntu LTS.
But as far as which version has the newest packages then sure, your list is correct.
