This is legit! I got it up and running in less than 20 minutes. Couldn't find the mutliversea repo. Also the steamcmd command executable was installed to '/usr/games/steamcmd' on Ubuntu 20.04.2 LTS. Last thing, I didn't have a 'steam' user so i just used my regular user and group and it works great. Thanks!
