[pkg-gnupg-maint] Bug#851462: Bug#851462: #851462 gpg-agent: a gpg-agent is already running - not starting a new one

[Daniel Kahn Gillmor]

Hi Thomas--

I'm sorry, but i don't understand what you're trying to do here.  I'm
re-closing this bug report (#851462) because it doesn't seem to be
related to the original report anyway, other than the string "gpg-agent
is already running" appearing in both of them.

I've asked you some questions below about what you're trying to do --
feel free to open a new bug report when answering them with a clearer
description (or to reopen this one again if you're sure this is the same
issue).

"to get the keys for both in" what?

why are you doing "killall gpg-agent" ?  what do you hope to gain from that?

what is "presign" ?  is that the script below?

the trace (below) doesn't seem to trace into this stuff, does it?  I
don't speak tsch fluently, and i don't understand what the SSH_ADD and
GPG_ADD environment variables are trying to do here.  can you explain?

Are you saying that /users/tom/.gnupg/gpg-agent.conf doesn't exist, but
gpg-agent is somehow claiming that it does?
