Hi Leo,

Leo Famulari <leo <at> famulari.name> skribis:

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’.
