Can you share the output of the following command (run as your normal
user):

   systemctl --user cat ssh-agent.socket ssh-agent.service


Here's what i'm seeing on my system:

```
0 dkg@bob:~$ systemctl --user cat ssh-agent.socket ssh-agent.service
# /usr/lib/systemd/user/ssh-agent.socket
[Unit]
Description=OpenSSH Agent socket
Documentation=man:ssh-agent(1)
Before=graphical-session-pre.target

[Socket]
SocketMode=0600
ListenStream=%t/openssh_agent
ExecStartPost=/usr/bin/systemctl --user set-environment SSH_AUTH_SOCK=%t/openssh_agent
ExecStopPre=/usr/bin/systemctl --user unset-environment SSH_AUTH_SOCK

[Install]
WantedBy=sockets.target

# /usr/lib/systemd/user/ssh-agent.service
[Unit]
Description=OpenSSH Agent
Documentation=man:ssh-agent(1)

[Service]
Environment=SSH_ASKPASS_REQUIRE=force
# If you need to pass extra arguments to ssh-agent, you can use "systemctl
# --user edit ssh-agent.service" to add a drop-in unit with contents along
# these lines:
#   [Service]
#   ExecStart=
#   ExecStart=/usr/bin/ssh-agent -D -t 1200
ExecStart=/usr/bin/ssh-agent -D
0 dkg@bob:~$
```

If your output looks the same as above, can you share the output of:

    systemctl --user status ssh-agent.socket ssh-agent.service

That would let me see what your local process supervisor believes is
going on with this service.

How are you restarting the ssh-agent user service?
