Hi,

This is what happens when /etc/profile isn't sourced in the remote
non-interactive shell on guix copy.

I find it difficult to understand.  I think the error message should
lead us to a way to fix the issue.

Do you know specifically which environment variable was missing and what
caused the backtrace?

Also, what commit are you using?  I=E2=80=99m asking because commit
ed7b44370f71126087eb953f36aad8dc4c44109f changed the way we talk to a
remote Guix over SSH.

I agree the message could be=E2=80=A6 ahem=E2=80=A6 clearer.  :-)

I don't know.  (I can't test right now.)

It was 627e6d8c116573e4d76a4548282532cfe3c97d54, so I had the recent
changes.
