Well, quite old and probably explain such trouble: https://launchpad.net/ubuntu/+source/light-themes Adwaita is the ubuntu default since a while.
Recent naming is 'ubuntu-themes' which provide 'light-themes' and others https://launchpad.net/ubuntu/+source/ubuntu-themes/16.10+16.10.20160829.3-0ubuntu1
So better report against 'ubuntu-themes' nowadays
