Hi @adil_kambal and welcome to the forum

What version did you install?
Docker or the standalone installer?

Please note, the standalone installer supports Ubuntu 16.04 Server ONLY ( before Ubuntu switched to systemd basically )

If you want to install on newer versions, please use the docker installation method.
