Build failure: tectonic

[dtomvan]

Nixpkgs version

• Unstable (25.05)

Steps to reproduce

• inputs.nixpkgs: github:nixos/nixpkgs/0196c0175e9191c474c26ab5548db27ef5d34b05?narHash=sha256-WGaHVAjcrv%2BCun7zPlI41SerRtfknGQap281%2BAakSAw%3D which is latest nixos-unstable as of writing
• home-manager switch --flake github:dtomvan/puntbestanden/3724c00aa270cf7282680181b3638d971efea6d8
• /nix/store/w72rddnkj781b3mivkj6jxxllkcclvh6-tectonic-0.15.0.drv gets built at some point from nixpkgs.legacyPackages.x86_64-linux.tectonic

OR: nix build github:nixos/nixpkgs/0196c0175e9191c474c26ab5548db27ef5d34b05#tectonic

Although this also happens with master...

Can Hydra reproduce this build failure?

No, Hydra cannot reproduce this build failure.

Weirdly enough a version of tectonic-wrapped just got built and it worked fine: https://hydra.nixos.org/build/291096374

Additional context

I feel like I just got a wrong version of nixpkgs. I just updated because I wanted to try Plasma 6.3.1, but a whole lot needed rebuilding so I reckon I should just downgrade again, but I still think this report is relevant...

Ah, great! You guys are so quick with it, huh? This'll close automatically, so I'll keep it open for consistency.

Edit: almost forgot to say thanks, so thank you for maintaining the package.
