On Ubuntu 15.04 (Vivid Ververt) the installation of the package openssh-server displays the following error message:

initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

Running 'systemctl status ssh' shows that systemd knows about the service:

It appears that sshd is attempting to register with upstart and with systemd. SInce Ubuntu 15.04 upstart has been replaced with systemd. I expected openssh-server on Ubuntu 15.04 to not want to use upstart. It does properly use systemd, it just prints an error about trying to tallk to upstart.
