Depois de ter um monte de pesquisa no google, finalmente consegui instalar o pip3 na minha máquina do Ubuntu 16.04 simplesmente executando estas linhas de código
1. sudo apt-get install python3-setuptools
2. sudo easy_install3 pip
Quando executo o commannd sudo apt install python3-pip
no Ubuntu 16.04, recebo esses erros

Você quebrou os pacotes, portanto, siga estas etapas:
Corrigir pacotes quebrados:
sudo apt -f install
Atualização:
sudo apt update && sudo apt dist-upgrade
Agora instale normalmente:
sudo apt install python3-pip
Verifique se ele está instalado:
pip3 --version
Isso deve corrigir isso.
