Css for admin page does not load

I have installed sonata and ran

php app/console assets:install

All resources seems to install correctly but when I go to:

domain/app_dev.php/admin/dashboard

I am presented with this:

As you can see from the image all requests load except the one for font-awesome.min.css but the file does not exist anywhere in Sonata.

I also ran

bower install ./vendor/sonata-project/admin-bundle/bower.json

but that didn’t fix anything.

What am I missing???

NOTE: In the AdminLTE github project there is no font-awesome.min.css file. You can view the project here: https://github.com/almasaeed2010/AdminLTE/tree/master/dist/css
