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:
 libsdformat-dev : Depends: libboost-regex-dev but it is not going to be installed

Кажется, что libsdl установка не была успешна. При поиске о libsdl существует две версии libsdl1 и libsdl2. Я думаю для нахождения некоторых других способов установить их. У кого-либо есть совет для установки?

@steeldriver:I сделал Ваше предложение, и вывод был followings:

$ sudo apt-get update && sudo apt-get upgrade
finished...

$ sudo apt-get install libsdl1.2-dev

Решенный предложением doug

Open up Software & Updates > Updates tab & make sure that 
the first 2 are enabled. (- trusty-security, trusty-updates). 
If one or the other wasn't enabled then do so, 
after that reload sources & proceed.

Спасибо за Ваше решение, doug! Благодаря всем, кто участвовал в этой проблеме особенно steeldriver и A.B.!
