bug#40125: Problem with guix offload: Remote channel closed

[Mikael Djurfeldt]

Hi Ludovic! :-)

I did generate the signing key on wand. (But is this sensitive to what user I used? O might have done it as root rather than as the ssh user used to login on wand.)

I will look at the other buh reports. Meanwhile, do you have any hint on where to look/insert logging code in order to see what is going on?

Best regards,

Mikael

Did you generate a signing key on wand.pdc.kth.se?  Specifically with:

  sudo guix archive --generate-key

(See
<https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-archive.html>.)

Error reporting in guix offload is currently suboptimal as you have
seen.  There’s a couple of bug reports open on that topic, so hopefully
we’ll get there soon!
