Installing on Ubuntu 15.04 Gives Upstart Error

I have been trying to install Gitlab on a instance of Ubuntu 15.04.

Unfortunately when I run:

sudo gitlab-ctl reconfigure

I get the error message:

STDERR: initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

I solved this locally by amending the rule in /opt/gitlab/embedded/cookbooks/runit/recipes/default.rb

when "debian"
  case node["platform"]
  when "debian"
    if node["platform_version"] =~ /^8/
      include_recipe "runit::systemd"
    else
      include_recipe "runit::sysvinit"
    end
  else
    include_recipe "runit::upstart"

to

when "debian"
  case node["platform"]
  when "debian"
    if node["platform_version"] =~ /^8/
      include_recipe "runit::systemd"
    else
      include_recipe "runit::sysvinit"
    end
  else
    #include_recipe "runit::upstart"
    include_recipe "runit::sysvinit"

Perhaps there would need to be a check for Ubuntu, and the particular version of Ubuntu....?
