Need Help With Installation

So I have been sitting here for around 8 hours trying to install GitLab with no such luck. I have been using tons of different install instructions, and keep running into errors. Is there anyone who would be willing to install it for me? This would be a tremendous help. My Skype is mandler119 for contacting. II need it done in either Debian, Ubuntu, or Centos.

What steps did you follow? Installation is like 4 steps if you use the package

The hard part would be the configuration.

I do that and I keep running into an error with the last step. It says it has trouble creating the git user.

Can you paste here the output?
