guix deploy: “unknown error”

guix deploy: “unknown error”

[Ricardo Wurmus]

Hi,

I’m getting an unhelpful error when trying to deploy from my x86_64
laptop to an i686 system:

--8<---------------cut here---------------start------------->8---
$ guix deploy deploy.scm
guix deploy: deploying to elephly...
sending 0 store items (0 MiB) to '192.168.178.20'...
Backtrace:

Does “status: 44” mean anything to someone here?  I used strace on the
short-lived “guix repl” process on the remote but I don’t see anything
wrong.  The process ends after determining that no files need to be
sent:

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

3582  read(13, "stla\0\0\0\0", 8)       = 8
3582  read(13, "\1\0\0\0\0\0\0\0", 8)   = 8
3582  write(13, "\1\0\0\0\0\0\0\0007\0\0\0\0\0\0\0/gnu/store/vlpabz0q67c7h1vcbrgfk6fchi64gmk1-guile-2.2.6\0", 72) = 72
3582  read(13, "stla\0\0\0\0", 8)       = 8
3582  read(13, "\1\0\0\0\0\0\0\0", 8)   = 8
3582  close(13)                         = 0
3582  write(1, "(values (value ()))\n", 20) = 20
3582  read(0, "", 4096)
…
--8<---------------cut here---------------end--------------->8---

(Note that I had to append GUILE_* environment variables to
/etc/environment on the target to get this far.)

This is coming from ssh.scm send-files, when the result can't be
matched by other clauses. I did not dig too deep into it, maybe we
could try to print the result there...
