Как обновить pip3 подверсию?

Я обновил свой сервер Ubuntu от 15,04 до 16.04 LTS недавно. В процессе, Python 3.5 был установлен. Однако версия pip3, который идет с ним, по-видимому, хочет использовать python 3.4 по некоторым причинам, не python 3.5.

Вот ошибка, которую я вижу:

- удар:/usr/local/bin/pip3:/usr/bin/python3.4: плохой интерпретатор: Никакой такой файл или каталог

Как я могу установить соответствующую версию зернышка для работы с моей установкой python 3.5?

Вот пакеты Python, которые я установил (найденный через sudo apt list --installed | grep python):
