Propspect : When upgrading to the next stable version of Qubes 4.0XXX

[brutelle...@gmail.com]

When there will be a stable supported version of Qubes 4., and I upgrade, will I be able to keep all my set ups and docs on each on my VM's ?

Or will I have to wipe it all in order to upgrade and install the new version ?

If you're upgrading from 3.2 to 4.0, a clean reinstallation will most
likely be required (or at least highly recommended). However, if you
migrate using Qubes' backup and restore tools, your data and settings
within each domU will be preserved.

Here you go, https://www.qubes-os.org/doc/releases/4.0/schedule/
Keep an eye out for release timetable updates here too, as you can see it had revisions and updates in the past, some may come in the future too. You find this link for the time tables directly below the download section on the official website, for all Qubes releases both past, current and the future releases to come. But currently, these are the official estimated release days given out by the Qubes team.

Also a warning, don't do what I did! Frankly it's a bit embarrassing, since it's pretty obvious, but really, do not backup-restore any templates from Qubes 3.2 to Qubes 4... This worked just fine from Qubes 3.2. to another Qubes 3.2., but it won't work very well from Qubes 3.2. to Qubes 4, because the Qubes tools installed inside the VM's are different in their code between versions, and therefore not compatible (guessing from experience and hardships, I did not read the code though). At the very least, it gave me a lot of trouble, and it's at least partly explaining why qvm-run and qvm-open-in-vm did not work (partly). Seemingly Fedora templates work flawlessly now, if one does not do this mistake, but the debian template is still troublesome for some people (note: some people, not everyone), even if you re-install it.

But aside from things like that, and as long as you can fall back on backups in case something goes wrong or you can spend time to try repair, then Qubes 4 is in my experience pretty stable now after some updates have been released. But this is mostly the common bugs everyone experienced, the uncommon bugs might possibly still give some people big issues, so you still need to watch it and be careful not to loose data or time, each hardware is unique and has its own personality, so to speak.

Experiment with it, see if it's stable, and then make a decision whether you feel comfortable with it or not.

Also another warning, ff you plan to install Qubes 4 while retaining QUbes 3.2. on the same machine through UEFI/EFI. You'll clear the EFI entry in the motherboard boot settings. At least i did not have much luck to use efibootmgr to restore my xen efi again, which always worked flawlessly in Qubes 3.2. So you need to have proper backups in place, just to be safe. On the other hand, Qubes installed through legacy BIOS boot appears not to have such issues though.

Also be sure you meet the minimum requirements, as Qubes 4 is much more strict regarding having the hardware security features. Qubes 3.2. was more lax in this regard, so even if Qubes 3.2. worked, Qubes 4 may not. Have a look here https://www.qubes-os.org/doc/system-requirements/

Thank you for such a detailed reply Yuraeitha !

This was the occasion to see the laptop I specifically got to run Qubes very recently isn't listed as compatible with Qubes 4... ! It's not listed as incompatible either, just no information. But I can just try it myself when the times come.

Perhaps I should checked that out before.

Anyway this was such an adventure to make it run properly for what I intended to do with it (an adventure I don't regret a single bit because it taught me some new things), that I wasn't really planning on upgrading it tomorrow...

Hope to be able to use it a bit more before it becomes obsolete security-wise.
