Public bug reported:
I use an authentication subkey of my GPG key on my Yubikey hardware
token as my SSH key. This works fine in Bionic with gpg-agent's ssh-
agent support, and, until a couple of weeks ago, worked fine on Cosmic.
Now it fails (GPG *signing* works fine), complaining about “invalid
ioctl for device” in the journalctl logs.
This turns out to be an environment issue - running
```
systemctl --user set-environment
DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS
systemctl --user restart gpg-agent
```
results in a working pinentry popup, and successful authentication for SSH
sessions.
Either gnupg has changed to require this environment for its ssh-agent
support, or systemd has stopped exporting this environment variable into
user session units.
