The systemd unit file from debian looks like that
(I only added the https_proxy, with localhost or 127.0.0.1, with or
without the leading http://):

#+begin_src conf :tangle "/etc/systemd/system/guix-daemon.service"
# This is a "service unit file" for the systemd init system to launch
# 'guix-daemon'.  Drop it in /etc/systemd/system or similar to have
# 'guix-daemon' automatically started.

After reloading the daemons and restarting the daemon :

guix pull: error: failed to connect to `/var/guix/daemon-socket/socket': Connection refused

By the way, I previously tested the proxy itself via wget and it
works. I also tried some others variations on the unit file without more success.

I'm not very familiar with the Debian Guix package, but can you check
that /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon does
indeed exist?  If not, you may need to log-in as root, and run `guix
pull` there.  Did the systemd unit ever work, and if not, how do you run
the Guix daemon?

Best,

Thanks for your help Josselin.

I precise that I am able to run guix in a debian standaloneVM without proxy.

I feared to have messed up something in that template so I started again
from scratch.

- I modified /usr/lib/systemd/system/guix-daemon.service and
  /usr/lib/systemd/system/guix-publish.service to use
  https_proxy=http:///127.0.0.1:8082

- /var/guix/profiles/per-user/root/current-guix doesn't exist.

> If not, you may need to log-in as root, and run `guix pull` there.
- guix pull (as user or root) :

#+begin_exemple
Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...
guix pull: error: Git error: failed to resolve address for
git.savannah.gnu.org: Temporary failure in name resolution
#+end_exemple


I am still able to use my proxy with wget.

- guix-daemon.service is now running without error.

- guix-publish.service throw an error (but I guess it is another issue):
