I would get the .drv file name of that thing and then do: guix build --log-file /gnu/store/…-qemu-minimal.drv \ --substitute-urls=https://berlin.guixsd.org This should give you the URL of the failed build. Alternately, you can also go directly to: https://berlin.guixsd.org/log/XYZ-qemu-minimal where “XYZ-qemu-minimal” is the *output* file name of that thing (not the .drv file name.) If that is 404, then most likely the thing was never built. To determine why, one would have to inspect /var/log/cuirass.log from berlin… HTH! Ludo’.
