 shawn8901 | Hi,
Could it be, that the Github Status Plugin is currently not working as expected? Since some time i am missing the reported build status for my flake on github.
The error message according hydra-notify is the following:
Sep 16 18:22:56 tank hydra-notify[2039]: Flake is github:shawn8901/nixos-configuration/28dbe4cc7f9b036bb7a3fc37a22b08730f48df0d?narHash=sha256-BeuUHKxtlcnweo9c2rZLRABgIv2ARBUXfySQ6MJDxQA%3D
Sep 16 18:22:56 tank hydra-notify[2039]: Can't parse flake, skipping GitHub status update
https://github.com/NixOS/hydra/blob/274027eb504c7fe090e00c16fd94f4b832981095/src/lib/Hydra/Plugin/GithubStatus.pm#L100
Which is right according the regex, tho i am not seeing what should be wrong on my end, it looks to me that the narHash that is in the url is unexpected.
My jobset definition is here: https://github.com/Shawn8901/nixos-configuration/blob/b1f6e066c77c4eb078bcf873bf6e7eeb3a91db16/.hydra/jobsets.nix#L28
And i dont see where i could cause the narHash to be included and i asume its more a internal issue here.

so the config part of the issue seems unrelated and its more the 2nd part about the url.
I assume issue author did later just use the git url variant, but i dont think that this is a proper solution as the github url is quite nice to use.

| shift | Anyone care to take a look at https://github.com/NixOS/hydra/actions/runs/17803795081/job/50610337495?pr=1524 and let me know where I messed up? | 16:21:34 |
| shift | Finally a PR I authored which passes CI, and is something people have complained about for a while :D https://github.com/NixOS/hydra/pull/1525 (feat: Lazy-load Build Steps and RunCommand Logs tabs) | 17:16:52 |

| Mic92 | Sandro 🐧: did you were doing ca stuff with nix 2.31 when you reported your issues? | 21:35:11 |
| Mic92 | I recored the output with sysdig -c stderr | 21:35:42 |
 Sandro | I think, yes | 21:38:28 |
| John Ericson | Sandro 🐧: going AFK, but please dump what you know here (or link if if you already wrote it) | 22:37:56 |
| Sandro | Initially it broke when updating to 2.31 but since I deployed the 2.30.4 (IIRC) update I either broke something else or it broke also. I need to see if I can revert the last or multiple flake bumps. All the builds I tried building with nix-build succeeded but even then the build by Hydra fails | 22:42:22 |
| John Ericson | ok thanks | 22:44:12 |
| John Ericson | I see the builder is killing the process thinking it's failed | 22:44:25 |
| John Ericson | (unless that is ssh killing but doubt it) | 22:44:34 |
| John Ericson | but I don't know why | 22:44:36 |
| 23 Sep 2025 |
| Sandro | It's happening with the localhost special name which shouldn't use ssh | 06:13:29 |
| Sandro | sysdig is not saying much useful
