Tienes paquetes rotos, así que sigue estos pasos:

1. Reparar paquetes rotos:

   sudo apt -f install
   

2. Actualizar:

   sudo apt update && sudo apt dist-upgrade
   

3. Ahora instale normalmente:

   sudo apt install python3-pip
   

4. Comprueba si está instalado:

   pip3 --version
   

Eso debería solucionarlo.

Después de buscar mucho finalmente esto me funciona.

sudo apt-get install aptitude

Luego instale pip3 con este comando:

sudo aptitude install python3-pip
