Glad it worked now.  What was the original system specifications?  I
suspect a lack of RAM, perhaps.

That's a good suggestion, but I'm guessing difficult to implement ('guix
pull' may complete with very little memory used or a lot, depending on
the availability of substitutes).

For you specific needs (low specs), I'd suggest using this your
~/.config/guix/channels.scm file:

--8<---------------cut here---------------start------------->8---
     (use-modules (guix ci))

     (list (channel-with-substitutes-available
            %default-guix-channel
            "https://ci.guix.gnu.org";))
--8<---------------cut here---------------end--------------->8---

As documented in '(guix) Channels with Substitutes'.

I hope that helps,

Maxim
