NixOS 23.11 released!

[danielbarter]

I’ve found package aliza dissapearing in this release. Why would a package disappear, whats the point?

packages disappear because there is no one to maintain them. Your configuration can depend on multiple versions of nixpkgs, so you can still get the package that way.

i think it should stay in nixpkgs and depend on old revision. Because now I can’t search for it on the website. It might be my favourite package and I won’t install nixpkgs because of that.

EDIT: Ok, i dont know. Not sure about that.

Couple of things here:

1. aliza depends on qt4 which we no longer support
2. aliza was removed from nixpkgs before the release of 23.11
3. by disappear, if you mean “it just isn’t on my system after the upgrade and it didn’t tell me anything”, that cannot happen. You would have gotten an error telling you that “aliza has been removed, because it depended on qt4 and was unmaintained in nixpkgs”.

You can however, still install software from older nixos releases

i think it should stay in nixpkgs and depend on old revision

That’s not how nix works.

It was error: undefined variable 'aliza'
haskellPackages.cabal-plan had a nice descriptive one.

Anyway haha, thanks for the context!

thanks to all who contributed. The upgrade went smooth, was flawless

Question: in which NixOS release will flakes be enabled by default - is there a plan/duedate/roadmap?
Because even ‘zero to nix’ strongly recommends using it

Is there page somewhere that lays out the EOL policies for the releases?

I looked for this at one point as well, and didn’t find anything.

But I did ask a somewhat-related question here on Discourse and sort of got it cleared up:

What does it mean for an old NixOS release to be "deprecated"?

I’m wondering what it means in practice for an old NixOS release to be “deprecated” or “end of life”? You can find references to old NixOS releases being deprecated or end-of-life a few different places. For example, from the nixos-23.05 release announcement, it appears that nixos-22.11 is now deprecated: Also, from https://status.nixos.org/, you can see that nixos-22.11 is tagged as “Deprecated”, and nixos-22.05 is tagged as “End of life”: [image] However, I’m wondering if there is a cano…

Hey, @kvtb. From what I’ve researched in the past, I came across this RFC which was very informative about the current status of Flakes and what the roadmap would be.

TL;DR: CLI will be stabilised first, then flakes.

Moreover, you could track meeting notes that are released right here on discourse.nixos.org. They mention flake-related things from time to time which may give good info on what’s the latest status on them.

Also, this thread isn’t the right place to discuss this; so, if you have anything more to ask, feel free to create a new topic.

This marks my first major version upgrade after switching to NixOS 5 months ago (coming from 15+ years of MacOS). The process has been very easy and smooth so thanks to everyone for their dedication and effort in making this possible.

I just upgraded my entire home network. The upgrade was painless.
Thanks for everyone’s hard work to make such an exceptional operating system experience!

Super. Thanks. That did it for me.
My config is here (a newbie’s setup… )

A highlight of the release is GNOME 45, which introduced a new image viewer and a new camera app.

Unfortunately, the new camera app doesn’t work (Snapshot cannot play camera stream · Issue #261217 · NixOS/nixpkgs · GitHub) and the old camera app was removed (by default).
