Builds break over time[0]. Generally this is from big updates like gcc, glibc, llvm, openssl, etc. Most software which is maintained upstream and within nixpkgs is fine. But there's a bunch of "cruft" that you accumulate over time. [0]: https://hydra.nixos.org/jobset/nixpkgs/trunk https://hydra.nixos.org/jobset/nixpkgs/trunk P.S. The link above builds for x86_64-linux, aarch64-linux, aarch64-darwin, x86_64-darwin, which also contributes to the failure rate.
