 magic_rb | idk who i was talking to, maybe emily or aleksana but i was complaining about nix always copying my dotfiles to the nix store. So what happened just now is i did .dump of my nix DB, then .read into a fresh DB and it had 3 effects afaict:
- it shrunk from 599MB to 380MB ish
- nix GC completed no problem and it felt substantially faster on average, it wasnt randomly getting stuck
- nix no longer copies my dotfiles every time?

 dramforever | 1 can probably be done with vaccum | 19:06:59 |
| magic_rb | Probably | 19:54:28 |

| nh2 | I get IOT instruction (core dumped) with nix-prefetch-url (Nix) 2.18.1 on Ubuntu, expected?

| jonhermansen | I got a crash with Nix also on i686, but it was a very old release (last ISO I could find) | 01:19:56 |
| jonhermansen | @nh2 I tried looking at the ZIP metadata, but I wonder if there's something wrong with the file format? | 01:20:27 |
| jonhermansen | I meant to try grepping for "None" in nix src | 01:20:39 |
| jonhermansen | This zip file is references in the selenium-server-standalone package that is currently in nixpkgs master | 01:21:08 |
| jonhermansen | * This zip file is referenced in the selenium-server-standalone package that is currently in nixpkgs master | 01:21:22 |
| jonhermansen | 2.18.1 is a very old version I think | 01:22:48 |
| jonhermansen | You can install Nix on your Ubuntu system with the script at https://nixos.org/download/ and you may be able to see the more recent issue | 01:26:33 |
| nh2 | Hm indeed that's from 2023, I will update. I guess my nix comes from nix-env and does not get updated with general home-manager updates | 01:27:13 |
| jonhermansen | IIRC you can update nix with nix | 01:27:29 |
| jonhermansen | I'm not sure based on your setup, but the script should install Nix for you, if you want to stay on the safe side you can pick single-user mode | 01:28:22 |
| jonhermansen | you can have both versions installed side by side. | 01:28:41 |
| jonhermansen | * I'm not sure based on your setup, but that script should install Nix for you, and if you want to stay on the safe side you can pick single-user mode | 01:28:56 |

| dramforever | hmm, there should be a message before that | 01:30:06 |
| nh2 | My Nix was installed on Ubuntu in single-user mode 10 years ago, so I suspect I'm already using the method you're suggesting. Doing nix-env -iA nixpkgs.nix to get 2.28.4.
Indeed that fixed the core dump, so probably not an issue anymore | 01:31:01 |
| nh2 | was downloading 'https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar' but nothing else | 01:31:07 |
| nh2 | jonhermansen: thanks for pointing out the old version, as a reward I confirm your bug from the other channel:
% nix-prefetch-url 'https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar'
error: failed to get libarchive filter by name: No such filter 'None'
| 01:31:37 |
| jonhermansen | Thank you for trying it, actually its helpful to know its not just me. | 01:32:17 |
