I'm sorry as well - with update I thought you meant updating the 
existing release but you were referring to a release update…

It has been mentioned already that you created /var/run/sshd in memory 
only. That's why the init script used to create the directory. On my 
15.04 partition there is still this section in "/etc/init.d/ssh": 

check_privsep_dir() {
    # Create the PrivSep empty dir if necessary
    if [ ! -d /var/run/sshd ]; then
        mkdir /var/run/sshd
        chmod 0755 /var/run/sshd
    fi
}

This should create the missing directory if necessary. Maybe your 
installation of sshd is broken? I would suggest to reinstall the 
openssh-server package.

BTW: The ssh server is a common part of all *Ubuntu flavours. Therefore 
it might be useful to also ask on the ubuntu-users list. I think there 
are several people who are already familiar with systemd.
