Mistakes in Installation page

We recently redid our Installation page (!5607 (merged)) and redirected /downloads page to it. There are few problems

1. We now show one single set of instructions for an OS family. For example, there is no separate instruction set for Debian 7 or Debian 8 (and upcoming Debian 9). There is a single "Debian" tab and that apparently uses "Debian Jessie"'s instructions.

• This fails when it comes to manual installation steps. Because we chose "Jessie" as the canonical instruction, it fails if users of Wheezy or Stretch tries to run them. The manual installation step is version dependent and we must separate them.

2. In manual instructions, a newline is missing between the curl command and dpkg command. Those are actually two separate commands.

added documentation installation labels

There's also a missing newline in step #2 (closed) in https://about.gitlab.com/installation/#debian I think there's supposed to be a newline after executing the piped script and installing the GitLab package.

i.e.

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bashsudo apt-get install gitlab-ce

should be:

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
sudo apt-get install gitlab-ce

i'm not really sure how to solve #1. @luke it probably needs the design re-thinking a little.

I can have a look at the new lines though

@iamphill could we make a simple update like so to include versions for the manual installation?

There is another problem as well, RPI2 builds are only available for EE. It shows a blank screen for CE, and you can't switch.

For the debian issue, it also affects ubuntu. I would suggest and have opened an MR that we simply delete the partial URL. It's not there in the enterprise instructions, as far as I know no issue has been opened to add it.

Since you already have to go look at the version strings from packagecloud, its essentially easier to just download or copy the URL from there.

I have opened an MR to do this: https://gitlab.com/gitlab-com/www-gitlab-com/merge_requests/6539

@iamphill can you review?
