Systemd:“单元”部分中的未知左值“用户”

A couple weeks a go I moved from Ubuntu 14.04 to 16.04 and found my Upstart script no longer worked, so feeling adventurous I managed to create a Systemd script that worked instead.

But I'm having a couple issues still.

[/etc/systemd/system/ss13_server.service:3] Unknown lvalue 'User' in section 'Unit'

This is my Systemd Script:

[Unit]
Description=ss13_server
User=ss13
[Service]
WorkingDirectory=/home/ss13/ss13
ExecStart=/usr/local/byond/bin/DreamDaemon /home/ss13/ss13/baystation12.dmb 25565 -trusted
Restart=on-failure
RestartSec=90s
