Проблемы с Установкой пакетов - Ubuntu 16.04 TLS

Я плохо знаком с Ubuntu и испытываю затруднения при установке некоторых пакетов на 16,04 TLS. Первый является зернышком. Когда я работал sudo apt-get install python-pip, Я добрался:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libpcl1.7 : Depends: libpcl-people1.7 but it is not going to be installed
 python-pip : Depends: python-pip-whl (= 8.1.1-2ubuntu0.4) but it is not going to be installed
          Recommends: python-all-dev (>= 2.6) but it is not going to be installed
          Recommends: python-wheel but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Я попробовал команду -f флаг, но тем не менее это не помогло. Я затем пытался установить использование libpcl-people1.7 sudo apt-get install libpcl-people1.7, но я получил еще больше ошибок:

Я обновил систему, прежде чем я выполнил эти команды. Мне ошибки просто выглядят странными. Какова могла бы быть причина для этих ошибок? Любая справка ценится.Спасибо.
