Hi,

this is a bit weird. It might be a duplicate of #798956

SSH support is broken with the instance of gnupg-agent that is started
via Xsession. The environment is set up correctly, i.e.
SSH_AUTH_SOCK=/home/jojo/.gnupg/S.gpg-agent.ssh
the process listens on that socket (verified using lsof) and accepts a
connection there when I run ssh. But ssh seems to be unable to
communicate with the agent and behaves as if it had no valid key.

The interesting thing is that after
killall gpg-agent && gpg-agent --daemon
during a running session, everything works fine.

The arguments passed to gpg-agent (--daemon) are the same as with the
initial process.

Any ideas what might be causing this?

Greetings,
Joachim
