offloading trouble on GuixSD->Debian

Hi,

I have run into yet another familar(?) problem with offloading.

My build host for the first time is Debian, so instead of GuixSD master offloading
to an GuixSD build node I'm offloading from GuixSD master to an Debian build
node.
This is a minimal, basic Debian install in the Hetzner cloud.

I've come as far as:

user@abyayala ~$ guix offload test
guix offload: testing 1 build machines defined in '/etc/guix/machines.scm'...
guix offload: 'yt' is running guile (GNU Guile) 2.2.3
offload: error: Guile modules not found on remote host 'yt'
hint: Make sure `GUILE_LOAD_PATH' includes Guix' own module directory.  Run
`ssh yt env | grep GUILE_LOAD_PATH' to check.

On the serer itself, the Guix modules are in the path.
Guile-ssh, guile, and guile-readline are installed in the profile of the
offloading user on the build node.
guix pull has been run at least once for the user profile.

~/.bashrc ends with:

source /etc/profile
GUIX_PROFILE="$HOME/.guix-profile"
. "$HOME/.guix-profile/etc/profile"

and I have created .bash_profile as Debian just provides .profile

I have experimented with the content of files and what is exported.

ssh yt env | grep GUILE_
GUILE_LOAD_COMPILED_PATH=/gnu/store/63p2z4sx3j6y8xs4sff423fl12qh1m0p-profile/lib/guile/2.2/site-ccache:/gnu/store/63p2z4sx3j6y8xs4sff423fl12qh1m0p-profile/share/guile/site/2.2
GUILE_LOAD_PATH=/gnu/store/63p2z4sx3j6y8xs4sff423fl12qh1m0p-profile/share/guile/site/2.2

The "guix" package must be available on GUILE_LOAD_PATH.

Does 'guile -c "(use-modules (guix))"' work for the offloading user?

As I've written, yes, locally it works (guix is available when I log in via ssh and
execute the command for guile to use the module). via remote non-interactive shell
it doesn't.

Are the Guix modules actually present at those paths in
"/gnu/store/63p2z4sx3j6y8xs4sff423fl12qh1m0p-profile"?  You can find out
by running this command on the Debian host:

find -L /gnu/store/63p2z4sx3j6y8xs4sff423fl12qh1m0p-profile -name guix

If they aren't present, then according to the "guix offload" hint,
you'll need to add the Guix modules to it.  One way to accomplish that
might be to add either the system installation or the build user's
installation of Guix (the latter should be at ~/.config/guix/latest) to
the GUILE_LOAD_PATH in your build user's ~/.bashrc on the Debian host.
Another way might be to run "guix package -i guix" as the build user on
the Debian host.

Hope that helps!  Good luck.

indeed, this returned an empty result.

None of the above worked,

but this did. Too bad, I wanted avoid installing guix into the profile.

You may want to set GUILE_LOAD_PATH and GUILE_COMPILED_LOAD_PATH in
/etc/environment on the target machine.

Also make sure to kill the Guile process that listens on the target
machine after making changes to the environment or else they won’t have
any effect.

I've read in an old thead that you've done this on a couple of machines,
I'll try it soon.
Thanks for the advice.

Glad it worked.  To figure out precisely why only the last method worked
for you, I guess it would be necessary to debug the exact logic that is
importing the modules.  It's probably somewhere in
guix/scripts/offload.scm, maybe?
