OK, apologies.

*reprepro* doesn't appear to support `pinentry-mode loopback`, for
whatever reason. But this is orthogonal to the substantial point...

I have tried this, and it makes no difference. I have also attempted to
work around the problem by killing gpg-agent entirely. But given that
`pinentry` is being passed the correct `display` option (as evidenced by
`ps ax`), the issue does not appear to be on the agent side.

If I run `pinentry --display $DISPLAY` inside my ssh session, and then
say `GETPIN`, it does not bring up a window. If I do the same in a local
terminal, it brings up the correct window.

The evidence would suggest that pinentry-gnome3 v1.1.0-2 on Debian
blindly uses `:0` no matter what parameters are passed.
