metasploit.service failed to load: No such file or directory!

Hi, I'm very new to Kali Linux, I saw a tutorial for metasploit guy in the video entered
service metasploit start and things started to load, but when I entered service metasploit start I got this error "metasploit.service: Unit metasploit.service failed to load: No such file or directory."

I've searched this error on google but I didn't find any solution, but I found this is a common problem.

Please help if you know how to fix this! Thanks!

Sorry if my English is not good, hope you understand!

And sorry if this is in the wrong forum section!

You no longer need to run "service metasploit start".
You can just run "msfconsole" after you have started postgresql and initialized the database.
