Recientemente actualicé mi servidor Ubuntu de 15.04 a 16.04 LTS. En el proceso, se instaló Python 3.5. Sin embargo, la versión de pip3 que viene con él aparentemente quiere usar Python 3.4 por alguna razón, no Python 3.5.
Aquí está el error que veo:
-bash: /usr/local/bin/pip3: /usr/bin/python3.4: intérprete incorrecto: no existe tal archivo o directorio
¿Cómo puedo instalar la versión adecuada de pip para que funcione con mi instalación de Python 3.5?
Estos son los paquetes de Python que he instalado (encontrados a través de sudo apt list --installed | grep python):

Descargué el get-pip.pyscript y lo ejecuté con python3.5. Hacer eso pareció aclarar las cosas.
