 guiniol | BTW, to pin version, I created new nixpkgs instances pointing to revisions found using https://www.nixhub.io/packages/unifi. AFAICT, it is working because I can see the versions changing in the systemd daemon files etc... | 20:41:38 |
 Dreamgineer | Generic answer here: I've locked myself out of my system many times, if rolling back doesn't fix it(in case of /etc/shadow issue), your best bet is probably grabbing a live USB and resetting the password there. | 20:43:12 |
| Dreamgineer | How did you install unifi exactly? | 20:44:03 |

Generic answer here: I've locked myself out of my system many times, if rolling back doesn't fix it(in case of /etc/shadow issue), your best bet is probably grabbing a live USB and resetting the password there. I can log into the system, but not into the unifi controller website | 20:44:13 |
| Dreamgineer | oh so just the website? | 20:44:22 |
| guiniol | In reply to @dreamgineer:matrix.org
How did you install unifi exactly? Using services.unifi | 20:44:47 |
| guiniol | In reply to @dreamgineer:matrix.org
oh so just the website? Yes. Local self hosted controller, with a local account (there is an option to use their cloud account but I do not want to do that) | 20:45:31 |
| Dreamgineer | There's an option to change JRE package, services.unifi.jrePackage. Have you tried that? | 20:46:57 |

There's an option to change JRE package, services.unifi.jrePackage. Have you tried that? Yes. Is there a recommended pastebin website? It'd be easier if I shared that part of my config | 20:48:25 |
| Dreamgineer | you can paste it here as codeblock if it isn't too big. | 20:48:50 |
| guiniol | here goes my flake.nix (at least the relevant parts): | 20:54:19 |

| guiniol | and the unifi module I have | 20:55:32 |
| guiniol |
| 20:55:42 |

};

| 20:56:34 |
| guiniol | Also, do I just open an issue on https://github.com/NixOS/nixpkgs if I can't figure this out? (I haven't found a relevant issue there, I did check). | 20:59:11 |
| Dreamgineer | I feel like this is related to the database file not being migrated to 10.1.x | 20:59:49 |
| Dreamgineer | or rather, mongodb version difference | 21:02:30 |
| Dreamgineer | #mongodbPackage = pkgs.mongodb-ce;
has this always worked before?
| 21:03:15 |
| guiniol | Yes, that was working. But even pinning to the version that the working build uses doesn't work now | 21:06:43 |
| guiniol | I thought so too initially, but even wiping the data folder and starting from scratch doesn't work. | 21:07:27 |
| guiniol | so now I don't think so anymore. I was thinking some crypto library that changed in java or something, but pinning java also didn't help and I'm not sure that I want to pin half the system libraries... | 21:08:49 |
| guiniol | also, I can't just run the older build because other parts of the system updated their databases and won't start on the older build. Because it'd be too easy otherwise. | 21:09:31 |

 just1602 | https://github.com/NixOS/nix/pull/15380
Wut? | 22:12:00 |
 piegames | Indeed | 22:58:14 |
| just1602 | I guess it's one way tro write stuff in rust without linking issue | 23:14:16 |
| piegames | Oh no that's something completely different | 23:20:42 |
| piegames | This is not about writing some of the Nix evaluator in Rust. This is about writing the Nix code which runs within the evaluator in Rust | 23:21:12 |
