I suppose that’s with Guile 2.0, right?

So the patch would become:

diff --git a/tests/guix-system.sh b/tests/guix-system.sh
index 4bb866adf..eaa0c4332 100644
--- a/tests/guix-system.sh
+++ b/tests/guix-system.sh
@@ -125,7 +125,8 @@ else
        # See <http://bugs.gnu.org/26107>.
        grep "$tmpfile:[49]:[0-9]: GRUB-config.*[Uu]nbound variable" 
"$errorfile"
     else
-       grep "$tmpfile:9:[0-9]: GRUB-config.*[Uu]nbound variable" "$errorfile"
+       # With Guile 2.0.14 the error is reported on line 14 (the last line).
+       grep "$tmpfile:9:[0-9]\+: GRUB-config.*[Uu]nbound variable" "$errorfile"
     fi
 fi
 

Please push if it works for you.

Thanks,
