Unable to enable first run wizard app on NC 12

Installed NC 12 on Ubuntu 14.04 LTS.

I have noted that the firstrunwizard does not come in the standard releases now so I have completed a git pull of the https://github.com/nextcloud/firstrunwizard repo into the apps folder.

For some reason the app appears as greyed out enabled button. I’m assuming there is something wrong with the app in my deployment and that is why I cannot enable it?

I also tried to copy the firstrunwizard/ app from abother instance of NC here that I have where it runs perfectly well! Very strang and a bit stumped here.

Any suggestions would be super.
