 oak 🏳️🌈♥️ | Actually I think it happens while regenerate-hackage-packages.sh calls regenerate-transitive-broken-packages.sh | 13:14:27 |
| oak 🏳️🌈♥️ | https://github.com/NixOS/nixpkgs/issues/400784 I see there's this issue which was closed by sterni last week, I was able to reproduce it :D I have nix (Nix) 2.28.4 | 14:08:19 |
| oak 🏳️🌈♥️ | * https://github.com/NixOS/nixpkgs/issues/400784 I see there's this issue which was opened by sterni which was closed last week, I was able to reproduce it :D I have nix (Nix) 2.28.4. I'm trying to update to 2.28.5 which seems to be the latest on stable | 14:11:55 |
| oak 🏳️🌈♥️ | Seems to happen also with Nix version 2.30.2 and 2.30.3, I first saw this on my macOS system and then I switched to NixOS to see it also happening there | 14:24:34 |

 sterni | darwin? | 21:04:11 |
| jean-paul. | nope, Linux - but CircleCI | 21:20:02 |
 Alex | In reply to @jean-paul.:matrix.org
nope, Linux - but CircleCI Just guessing, but is it because the kernel has IPv6 disabled via sysctl or perhaps even via kconfig?
Nix builds are sensitive to the host kernel. | 22:17:23 |

 teo (they/he) | I know the nixpkgs build of GHC edits the settings file, so I wanted to give y'all a heads up that the ghc-toolchain line of work is replacing the settings file, so it's likely that you'll need to make some changes here. See: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/14500 | 13:48:05 |

| jean-paul. | Seems likely I guess. I don't know how to learn about CircleCI's kernel configuration.
Annoyingly, zlib test suite also fails. Seems like that should be less sensitive to the kernel but 🤷 | 14:45:54 |
| jean-paul. | I assume more folks than me want to use Nix on CircleCI | 14:46:10 |
| sterni | Now I'm scared about arithmetic regressions in 9.10.3… https://github.com/Bodigrim/arithmoi/issues/223 | 14:58:30 |
| sterni | so far nothings else like that happened, though | 14:59:08 |
