On Ubuntu (at least from version 16.x Xenual Xerus), create the above file as a normal user, then install it with:

sudo mv autossh.service /etc/systemd/system/

Enable as follows:

sudo systemctl enable autossh.service

After=network-online.target ssh.service

Also add

Environment=AUTOSSH_GATETIME=0

in the [Service] section if you experience problems like autossh.service: Start request repeated too quickly..
