Can't find the gitlab-debian.conf on RPI3

Hi there,

I tried to install Gitlab on the Raspberry PI 3 but the installation doesn’t work for now.
I’ve followed some tutorials on the web, but at the end the install, I’ve always the same message :

Can’t open /etc/gitlab/gitlab-debian.conf

Because of that, the gitlab-ctl command is not installed, and I can do nothing.
I’ve search the web for a solution, with no success for the moment.
As someone already had encounter the problem ?
