 emily | the flakes docs do say "btw don't care about nixpkgs duplication because everyone uses overlays" but uh, i would not say that that statement accurately describes existing practice | 09:07:47 |
| emily | (and in fact I think it was written before many were using flakes at all so it was really a prescription written as a descriptive statement...) | 09:08:03 |
| emily | this is certainly one of the awkward parts of the existing flakes design, imo | 09:08:21 |
 CRTified | For one-time use, having an old nixpkgs dependency is likely fine, while using it in a config makes overlays more useful | 09:08:26 |

the flakes docs do say "btw don't care about nixpkgs duplication because everyone uses overlays" but uh, i would not say that that statement accurately describes existing practice Yeah, I think I'm using modules and packages more than overlays, at least from flake inputs | 09:09:34 |
| * emily 's config uses 0 overlays in favour of packages outputs and tries to only evaluate nixpkgs once, but it's a bit of a pain sometimes. and of course sometimes you do actually need to override a dependency | 09:10:41 |
| emily | but i did, even in the pre-flakes days, sort of dislike using an overlay just to add leaf packages | 09:10:59 |
| emily | feels less structured | 09:11:18 |

| @adham-omran:matrix.org | Hey all I'm trying to rebuild my system after a flake update on the stable channel and I'm getting
error: Invalid package attribute path 'qt6Packages qt6ct'
Google was no help, any ideas what this means?

are you using home manager? | 11:49:50 |
| @adham-omran:matrix.org | In reply to @dariof4:matrix.org
are you using home manager? Yes | 11:50:31 |
| dariof4 | In reply to @adham-omran:matrix.org
Yes might be a mismatch between home-manager and your nixpkgs | 11:50:57 |
| dariof4 | e.g. you're using unstable home-manager while on nixos-23.05 | 11:51:14 |
| dariof4 | * e.g. you're using unstable home-manager while on nixpks/nixos-23.05 | 11:51:27 |
| @adham-omran:matrix.org | In reply to @dariof4:matrix.org
e.g. you're using unstable home-manager while on nixpks/nixos-23.05 Let me check that | 11:51:30 |
| dariof4 | * e.g. you're using unstable home-manager while on nixpkgs/nixos-23.05 | 11:51:38 |
| @adham-omran:matrix.org | Checked, both are 23.05 | 11:52:13 |
| @adham-omran:matrix.org | What else should I check? | 11:52:35 |
| dariof4 | hmm, are you using anything from unstable nixpkgs in your config? | 11:53:19 |
| @adham-omran:matrix.org | I grepped for unstable and nothing shows up in my .nix files | 11:53:46 |
| @adham-omran:matrix.org | I did used to use unstable but I switched to 23.05 when it was released | 11:54:36 |
| dariof4 | hmm, I think the issue is that something is trying to pull in qt6Packages.qt6ct which doesn't exist on 23.05, but exists on unstable | 11:55:46 |
| dariof4 | could I check your flake.nix? | 11:55:52 |
| @adham-omran:matrix.org | Yes

| dariof4 | In reply to @adham-omran:matrix.org
Yes
https://codeberg.org/adham/flake/src/branch/unstable/flake.nix you're using home-manager master, you should be using home-manager/release-23.05 if you're using nixpkgs/nixos-23.05 | 11:59:51 |
| dariof4 | the inputs.nixpkgs.follows just means that home-manager uses the same nixpkgs version, but some options in home-manager master may require packages which are not in nixpkgs/nixos-23.05 which leads to that failure | 12:00:43 |
| @adham-omran:matrix.org | Would following the trace lead to know which options they are exactly? | 12:01:36 |
| @adham-omran:matrix.org | Your explanation makes sense to me | 12:01:43 |
