Проблема в libassimp-dev мешает мне использовать apt-get

У меня конфликт пакетов. Кажется, что независимо от того, что я делаю, я не могу удалить оскорбительный пакет. apt-get действует как обычно, не удаляет пакет до тех пор, пока не будут разрешены все зависимости. Но я не могу разрешать зависимости из-за конфликта.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 ros-electric-assimp : Depends: assimp-dev but it is not going to be installed
 ros-fuerte-robot-model : Depends: libassimp-dev but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
