bug#29519: ./pre-inst-env: substitute: Failed to autoload make-session in (gnutls)

[Adonay Felipe Nogueira <adfeno@hyperbola.info>]

I'm experimenting developing directly to the Git checkout instead of
using GUIX_PACKAGE_PATH to develop and test package definitions.

Currently this is what I do:

--8<---------------cut here---------------start------------->8---
# If the local clone is somewhat dirty, clear it.
git reset --hard HEAD
git clean -fdx
# Uptdate the local clone.
git pull
# Use my already-installed Guix to prepare environment to hack on Guix.
guix environment guix
# Follow the info pages.
./bootstrap
# I checked contents of "/var" and it is indeed the localstatedir
# because "guix" (and gc lock, temproots and so on) is there.
./configure --localstatedir="/var"
# Do I need to do `make'? Since I'm used to do it I'll do it anyways.
make
# Back to following the info pages.
make check
--8<---------------cut here---------------end--------------->8---

Now I keep the first terminal open, and in a second terminal, I also go
to the local copy and do `guix environment guix', and keep that terminal
for now.

In a third terminal I stop the system's guix-daemon service, with
something similar to `sudo service guix-daemon stop'.

Then I go back to the first terminal, and do `sudo ./pre-inst-env
guix-daemon --debug --build-users-group=guixbuild', and that terminal is
now busy logging the daemon's activity.

In the second terminal I do `./pre-inst-env guix build --verbosity=4
hello' and I get this:

--8<---------------cut here---------------start------------->8---

acquiring read lock on `/var/guix/temproots/26301'

guix build: error: build failed: substituter `substitute' died unexpectedly
--8<---------------cut here---------------end--------------->8---

This also happens if I *don't* stop the already installed Guix daemon,
with the difference that in this case after stopping the ./pre-inst-env
guix-daemon, any further attempts to use the installed Guix daemon ---
even if no longer in the environment and even in a new terminal --- will
be denied, forcing me to restart this one.

In both cases (./pre-inst-env guix-daemon with installed guix-daemon
running or not), the ./pre-inst-env guix-daemon shows this:

--8<---------------cut here---------------start------------->8---
extra chroot directories: ''
automatic deduplication set to 1
listening on `/var/guix/daemon-socket/socket'
accepted connection from pid 26186, user adfeno
443 operations
--8<---------------cut here---------------end--------------->8---

I hope this helps finding out what the problem is.


Respectfully, Adonay.
