You may have noticed that hydra.gnu.org has been, hmm, unhealthy lately. There are several bugs in the offload hook that were fixed recently, notably fixing errors such as:
guix build: error: lstat: No such file or directory: ...foo.drv You may have also seen: derivation was garbage-collected prior to build This one should now be fixed, on the Hydra side: https://github.com/NixOS/hydra/commit/cc4645659896113cb8677110a1ed768405709296 So it’s not optimal yes, but making progress. Thanks, Ludo’.
