шаблон quick-ubuntu, показывающий неудовлетворенные зависимости и битые пакеты

Я пытался установить quickly-ubuntu-template, используя:

sudo apt-get install quickly-ubuntu-template

Вот что он вернул:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 quickly-ubuntu-template : Depends: python-pygame but it is not going to be installed
E: Broken packages

Помогите, пожалуйста?
