 graysontinker | Same issue here | 21:53:00 |
 Devin | probably related | 21:53:19 |
 hexa | 502 bad gateway is an nginx response | 21:53:34 |
| hexa | either harmonia is down or nginx can't access the unix socket | 21:53:48 |
| hexa | Redacted or Malformed Event | 21:54:01 |
| hexa | Redacted or Malformed Event | 21:54:10 |
 @busti:leitstelle511.net | Well, time to find out how long it takes my PC to build Blender | 21:54:19 |
| hexa | long. | 21:54:24 |
| hexa | enjoy | 21:54:27 |
| @busti:leitstelle511.net | It's been at it for 2 hours already :P | 21:54:41 |
| Devin | how on earth do i get rid of it as a substituter though 😠i can't build a new config with it disabled because of the 502 | 21:55:07 |
| @busti:leitstelle511.net | * It's been at it for 1 hour already :P | 21:55:25 |
| hexa | edit nix.conf | 21:55:51 |
 Gaétan Lepage | It's done indeed. I'm investigating | 21:56:19 |
 Winter | it should definitely fall back to your other substituters or building from source | 21:56:22 |
| Devin | just blows up | 21:56:36 |
| Gaétan Lepage | * It's down indeed. I'm investigating | 21:57:45 |
| graysontinker | Yeah, it just refuses to work. Looking at the code I'm not clear why though | 21:57:45 |
| Devin | can't edit nix.conf—it's generated by nixos and lives in the nix store so it's readonly | 21:58:05 |
| hexa | rm nix.conf | 21:58:25 |
| hexa | or rather | 21:58:29 |
| hexa | mv nix.conf{,.bak} | 21:58:33 |
| Devin | DUH | 21:58:34 |
| hexa | cp nix.conf{.bak,} | 21:58:41 |
| hexa | and edit :D | 21:58:44 |
| Devin | ty | 22:01:02 |
|  Melody joined the room. | 22:04:40 |
| Devin | okay so
