Running the commands in the log like below on my local trisquel machine
with guix triggers the same problem.  Any ideas?

(FWIW, the message is hidden inside the log, but the error and filename
of the log is printed in the gitlab log above, same as below; it is
possible to click on 'Job artifacts' to find the log files.)
