Unifi controller won't install

Hello all,
I have tried to install both the unifi plugin and manually install the plugin in a jail. Neither is working. When installing in a jail I get

pkg: No packages available to install matching 'unifi6' have been found in the repositories.

This didn't work with 5 either. I can install packages (for example vim) so not sure what the issue could be. Any help would be greatly appreciated.
