Issues with guix offload

Issues with guix offload

[Divan Santana]

Hi All :)

So my guix offload to my build box used to work, no troubles.

As of late it fails. Perhaps due to an update, or because I renamed the
user account on the remote box.

I think all is correct in terms of configuration but still fails with
the below.

Not sure how to further troubleshoot it:

~ sudo guix offload test
guix offload: testing 1 build machines defined in '/etc/guix/machines.scm'...
guix offload: Guix is usable on 'cp3.santanas.co.za' (test returned "/gnu/store/883yjkl46dxw9mzykykmbs0yzwyxm17z-test")
guix offload: 'cp3.santanas.co.za' is running GNU Guile 2.2.4
sending 1 store item (0 MiB) to 'cp3.santanas.co.za'...
exporting path `/gnu/store/sxxrzcpagpr87ldp82l9q634q7bbp8g5-export-test'
guix offload: error: unknown error while sending files over SSH

Seems something like this fails too

guix copy --to=cp3.santanas.co.za emacs

~ ssh ds@cp3.santanas.co.za guile --version
guile (GNU Guile) 2.2.4

~ ssh ds@cp3.santanas.co.za guix repl --version
guix repl (GNU Guix) 1.0.1-3.4a54ed7

Doing this (against sshd pid) on the build server results in a 2m file
output. Where can I upload that?

root@cp3 ~# strace -p 287 -s 300 -o log -f

Not sure what to look for in the log output.

Any ideas?

Hi Divan,

Did you eventually find out?

I would have suggested exactly this: look at the strace log, find the
bits that correspond to the ‘guix repl’ process, and see if there’s
anything wrong there.

Thanks,

I tried looking through the strace output but didn't come right with
that.

In the end I just built another box. Was easier to resolve.
