Hi, I'm trying to use "guix copy" to copy store items from host A to host B. Host A and B are both on the same LAN. Host A uses GuixSD, and host B uses Guix installed on Debian. No matter what I do, I get a message like the following:
--8<---------------cut here---------------start------------->8---
$ /gnu/store/xfrqrgazg0y7qn6k2d6psg5ssws4zs5w-guix-0.16.0-9.4bddd12/bin/guix
copy --to=192.168.1.105 /gnu/store/dpiq9gj0d8jd8qs0q9sdsm9npyjm684n-profile
guix copy: error: failed to connect to `#<input-output: channel (open)
26de6a0>': Protocol error
--8<---------------cut here---------------end--------------->8---
This appears to be emitted by code in (guix ui), and it seems to
indicate a problem related to the store connection, not the SSH
connection.
This happens even when I manually start the exact same version of
guix-daemon on the remote host, like this:
--8<---------------cut here---------------start------------->8---
$ sudo
/gnu/store/xfrqrgazg0y7qn6k2d6psg5ssws4zs5w-guix-0.16.0-9.4bddd12/bin/guix-daemon
--build-users-group=guixbuild
--8<---------------cut here---------------end--------------->8---
I've verified that I can connect to the remote host over SSH using a
command like this:
ssh 192.168.1.105
I've verified that I can invoke Guix's "open-ssh-session" to get a
usable session and run commands on the remote end:
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use (guix ssh) (ssh popen) (ice-9 rdelim)
scheme@(guile-user)> (define session (open-ssh-session "192.168.1.105" #:user
#f #:port 22))
scheme@(guile-user)> (define channel (open-remote-pipe* session OPEN_READ
"/usr/bin/lsb_release" "-d"))
scheme@(guile-user)> (read-line channel)
$1 = "Description:\tDebian GNU/Linux 9.7 (stretch)"
scheme@(guile-user)>
--8<---------------cut here---------------end--------------->8---
When I run guix commands on the remote machine, it works just fine:
--8<---------------cut here---------------start------------->8---
$ guix package --show=hello
guile: warning: failed to install locale
hint: Consider installing the `glibc-utf8-locales' or `glibc-locales'
package and defining `GUIX_LOCPATH', along these lines:
guix package -i glibc-utf8-locales
export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"
See the "Application Setup" section in the manual, for more
info.

--8<---------------cut here---------------end--------------->8---
The guix-daemon's socket exists in the usual place on the remote
machine, and it has appropriate permissions:
--8<---------------cut here---------------start------------->8---
$ ls -l /var/guix/daemon-socket/socket
srw-rw-rw- 1 root root 0 Feb 10 14:06 /var/guix/daemon-socket/socket
--8<---------------cut here---------------end--------------->8---
So what is this "protocol error" that keeps preventing me from using
"guix copy"? I've spent 2 hours trying to figure this out, so it's time
to ask for help.
