The #<unspecified> comes from the =E2=80=98node-eval=E2=80=99 code right ab=
ove line 281
of guix/ssh.scm.

Could it be that the (guix =E2=80=A6) modules were not found on the target
machine, or that guix-daemon was not running there?

Thanks,
Ludo=E2=80=99.

FYI, about 5 days ago I saw the same error occur on Hydra, during a
build offloaded to guix.sjd.se.  I reported it as bug #33722.

  https://bugs.gnu.org/33722

The relevant build aborted due to the error, but was later retried and
succeeded.  It's the only time I've ever seen this error, so I guess
the bug is relatively new.

Hi,

> Could it be that the (guix =E2=80=A6) modules were not found on the target
> machine[=E2=80=A6]?

That=E2=80=99s it!  The /etc/environment file does not contain lines for
GUILE_LOAD_PATH and GUILE_LOAD_COMPILED_PATH.  I added them manually,
killed the listening Guile process, and tried again =E2=80=94 with success.

I remembered that I added these variables to /etc/environment on all
build nodes for berlin.guix.info via a service like this:

--8<---------------cut here---------------start------------->8---
(simple-service 'guile-load-path-in-global-env
                session-environment-service-type
                `(("GUILE_LOAD_PATH"
                   . "/run/current-system/profile/share/guile/site/2.2")
                  ("GUILE_LOAD_COMPILED_PATH"
                   . ,(string-append "/run/current-system/profile/lib/guile=
/2.2/site-ccache:"
                                     "/run/current-system/profile/share/gui=
le/site/2.2"))))
--8<---------------cut here---------------end--------------->8---

Should this be done by default?
