[pkg-gnupg-maint] Bug#830658: Bug#834829: gnupg-agent: gpg-agent looses connection to usb dongle and stops working

[Norbert Preining]

Dear Daniel, deal all,

sorry for the late reply, I have now collected as many information
from your three emails.

Let us start with what I have done:
* activate default gpg-agent startup via systemd as decribed in
/usr/share/doc/gnupg-agent/README.Debian:
        systemctl --user enable gpg-agent

* reboot, login

after that the status is as follows:
* gpg-agent is running:
        /usr/bin/gpg-agent --daemon --homedir /home/<USER>/.gnupg
* ssh fails
[~] ssh <some-machine>
sign_and_send_pubkey: signing failed: agent refused operation
sign_and_send_pubkey: signing failed: agent refused operation
user at some-machine's password:

Done that, did not change anything:

[~] gpg-connect-agent updatestartuptty /bye
OK
[~]

>     gpg-connect-agent 'getinfo std_startup_env' /bye

[~] gpg-connect-agent 'getinfo std_startup_env' /bye

I do not have a directory/file "bus" in /run/user/1000/
probably because I don't have:

dbus-user-session installed.



Now for what I did and how I did it get running:

What works *without* any problems is starting
	gpg-agent --daemon
from Alt-F2 (run-me, whatever) in my DE (cinnamon).

That is the only thing that actually works.

Hope that helps

Norbert
