Failed to start opennebula.service: Unit opennebula.service not found

Hi! already installed Opennebula and had it running but wanted to use Mysql. I uninstalled trough apt-get, I’m using ubuntu 16.04 minimal. Now I reinstall it but when running “service opennebula start” I get Failed to start “opennebula.service: Unit opennebula.service not found.” Any clues would be much appreciated
