Grafana (grafana-server.service not found)

Hello, I have a question about installing Grafana. It was running at one point on my server. I uninstalled it and removed the service from /etc/systemd/system and /usr/lib/systemd/system

Now, whenever I install Grafana, I got: Quote:

Restarting grafana-server service...Failed to restart grafana-server.service: Unit grafana-server.service not found.

I've tried to use enterprise and oss. I also tried downloading deb (version 7.5.9 - 8.0.3) but nothing worked. I always got the same error message. There was no grafana-server.service in /etc/systemd/system either.

Please help.

OS: Ubuntu 20.04
