Hello! I'm having a problem on a Banana Pi M3 that runs Debian 10 Buster
(ARM like instruction set).
"guix pull" always results in failure with this message:

What can I do? Some help would be much appreciated. Thanks!

The signal 9 (killed) makes me think a C++ program killed. I checked
wikipedia and it says the Banana Pi M3 has 2GB of RAM. Was there
anything else running at the time? 'guix pull' can be resource
intensive, especially on lower powered machines.

Oh! Yes, of course, I see!
Yes, those little credit card sized one-chip computers are very low on
resources.
So I think it shouldn't build the programs itself but rather download the
binaries everytime I "guix pull". What command line option should I use to
only download the binaries instead of building everything myself? Could you
please give me the command?

You could try: `guix pull --substitute-urls="https://berlin.guixsd.org
https://ci.guix.gnu.org https://mirror.hydra.gnu.org"`. Since you are on
Debian, you should authorize the servers. More of the authorization
here:
https://guix.gnu.org/manual/en/html_node/Substitute-Server-Authorization.html.
You could always dry-run your commands to see if the substitutes work.

Actually, berlin.guixsd.org and ci.guix.gnu.org are the same server, and
mirror.hydra.gnu.org was decommissioned a while ago. The second server
for substitutes is https://bayfront.guix.gnu.org.

I think the best option would be to make sure you run 'guix pull'
targeting a derivation which has substitutes. If you check here¹ you can
see if there's a substitute already available for armhf-linux and run
'guix pull --commit=the-commit-listed-in-the-link'. Right now, that
would be 42a2ee1f9294614bd85892f2cc7318afb80b174c, which is actually the
latest commit.

If one has a powerful-enough pc or laptop on local ethernet,
is there a package that would set up a local user as simple builder-server
that the pi could download binary substitutes from?

Such a local server might have other uses as well, if browser-friendly :)
I'm sure you don't need help imagining that :)

Above sig reminds me:

BTW: if your Divine Emacs, like mine on debian-based distro , has recently been disrupted by Alt-Shift,
(probably because you have two kbd languages and emacs Alt '<' is Alt-Shift-comma on your en kbd)
stack-overflow had the recipe that worked for me. tl;dr in snip:

    disabling alt-shift toggling of us/sv ..
    read old value, write new value, read new value to check:
--8<---------------cut here---------------start------------->8---
    dconf read /org/gnome/desktop/input-sources/xkb-options
    ['grp:alt_shift_toggle', 'grp_led:scroll']
    dconf write /org/gnome/desktop/input-sources/xkb-options "['grp_led:scroll']"
    dconf read /org/gnome/desktop/input-sources/xkb-options
    ['grp_led:scroll']
--8<---------------cut here---------------end--------------->8---

Please excuse the off-topic BTW, but that bug cost me a lot of time,
so I hope that's useful to someone. Meta-question: how should one offer
hints like this so we can find them easily?

Seems like we need browsable open-gis/open-streetmap to map the ux territory and its potholes ;)

Indeed.  To help with this, you could wrap your main guix channel with
the `channel-with-substitutes-available'; see info '(guix) Channels with
Substitutes'.

Thanks,

I think it should be possible with 2GB of RAM, if you limit the number
of concurrent builds.

For example, something like `guix pull --max-jobs=1`.

And I think the memory requirements should decrease with the recently
released Guile 3.0.3:

For the record, I’ve successfully run the following command on my A20
OLinuXino with a bit less than 1 GiB of RAM:

  guix pull --commit=380c3e459b6ebf0077008886954ff881a0cc7924

It takes ages, but fortunately substitutes were available for this
revision.

Before substitutes were available, it went OOM (out of memory) as in
your case while building guix-system.drv.

‘guix pull’ is still barely usable on these low-end devices, though with
Guile 3.0.3 it’s better.
