hmm, I did not enable substitutes explicitly in the command line, but
as far as I remember, I allowed guix to use substitutes when I set it
up some time ago. Is there a handy command that helps me to check the
current configuration? Anyway, I was not using option --no-substitutes.

Hmm, shall I try
 guix pull --substitute-urls=https://ci.guix.gnu.org
next time?

Ahh, you are right. And please accept my apologies, as I did not see
the essential hint:

Indeed, at the time of failure, the root partition had only about 2.8G
space left. But /tmp had something like 9G in spare. I wonder if I can
tell guix to use as much tmp-space as applicable?

I will try to enlarge the root partition and try again.
Would you mind to give a recommendation for its size?

Thanks for your immediate, kind response!!
