Redmine

Hello,

I am after having a git server with redmine. I want the users to be able to create their repositories from redmine easly, by just selecting the identifier and that's it. I've learned about it where I used to work. So, I ran into the "Redmine Git Hosting" plugin and they suggest a different way to install redmine (http://redmine-git-hosting.io/how-to/install-redmine/) in the first place. I want to follow it because I managed to install and run redmine with apt-get but as this installs redmine in /usr and /var, the author of the plugin suggests to install it in /home where no root privileges are needed.

I started following the redmine installation guide, by creating a "redmine" user with disabled-password but when I am abothisut to install Ruby (step 3), it prompts this:

Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/16.04/x86_64/ruby-2.1.4.
Counting with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Cheking requirements for ubuntu.
Installing requirements for ubuntu.
Updating system. redmine password required for 'apt-get --quiet --yes update':

But as I created this redmine user with --disabled-password, obviously I cannot do that with redmine user. I changed to root, did apt-get update and apt-get upgrade, then switch to redmine (user) again, retried with rvm install 2.1.4 but got the same issue. Is there any option that I should have used to create this redmine user?

Thanks for the help.

EDIT 1: I have just managed to install redmine, I did the test suggested in step and it works, but if I stop this and then try http://localhost:3307 I get an "unable to connect" error.
