Debian 10 Buster became stable a few months ago, the rest of the systems had to follow but took their time. This is done every two years and creates a wave of confusion, especially those on forked versions of Debian, like antiX, MX, devuan, refracta, etc. Even more dangerous and confusing it is if you are using testing and although testing during debian stretch was buster it now becomes bullseye, while your antiX/MX/Devuan is testing alongside Buster still.
After antiX announced 19 (Marielle Franco) as its current stable branch, MS followed its mothership the week later (a few days ago), while Devuan/Refracta are still chasing Stretch (Debian 9), what they call Devuan 2 or ascii.
So here it is, to take the confusion away from numbers and names:
Debian * Debian * AntiX/MX * Devuan the last good1 * 7 Wheezy * 13 * 0 beta-testing old old stable * 8 Jessie * 15 * 1 jessie (old-stable) old stable * 9 Stretch * 17 * 2 ascii (stable) stable * 10 Buster * 19 * 3 beowulf(testing) testing * 11 Bullseye * 21 * 4 chimaera (next testing) unstable * sid * sid * ceres
As long as you are pulling packages from the same line you should be OK, if you are mixing and matching levels you are on your own, don’t ask for advise, you know better.
The packages for each level that come from debian and create trouble for the others (due to lack of systemd/systemd-libs/ and/or elogind & libs), are rebuilt by antiX and devuan and their numbering system supersedes debian’s, so they replace them as upgrades. In arch where you can have a hierarchy of repositories and a higher repository may have a lower version pkg and not get upgraded, things are much easier, but here we are dealing with the antiquity of apt/apt-get and the huge mess of debian repositories.
This chart is meant to take the confusion away from some, this is a popular source of endless debate on misunderstandings on debian based forums. We are not going to mention mint or ubuntu here, what they do and what their relationship to debian is, because they are simply irrelevant. Without Debian they are NOTHING! At least we give credit to debian and its TWO true forks, antiX and devuan.
** But you hate Devuan, why bother mention it? **
I don’t hate Devuan, I distrust Devuan’s repository system, and the explanations their “authorities” give to justify its mysterious ways. But this is a good opportunity to bring the subject UP again. Devuan -testing or Beowulf is following buster, right? For some time now there are NO UPGRADES, while they claim their repository is “merged” with Debian’s. How can antiX/Debian 19/buster rain updates every day almost, even at a minimal installation (no DM, openbox) but Devuan’s same branch is DRY? So it is not feeding Debian’s repositories, it is lying about it! When Devuan stops its upgrading (freezing) they freeze Debian as well. This is going on for a while now. If it wasn’t out of respect for Refracta and the man that brought (struggled to) OpenRC to Devuan I wouldn’t even bother knowing this is going on. But IT IS, and I WAS RIGHT, but they blocked and banned me out of their list and forum instead of giving a straight answer. Hence the distrust! The JUSTIFIED distrust in what they are mixing, why and how, and just feed as binaries to their users!
So what’s going to happen when they finally announce Devuan 3 Beowulf as Stable? You are going to make an installation and it is then going to rain 2-3 months worth of upgrades all at once, so it would be a waste of an installation bandwidth, really! So go with antiX, it is cleaner and more direct, more open in what it does and has nothing to hide. It is also free of this stack-up corporate/academic attitude “we don’t have to explain everything” I learned to hate about devuan.
My 2c really, what are they going to do, sue me?
