Você quebrou pacotes, então siga estas etapas:

1. Corrija pacotes quebrados:

   sudo apt -f install
   

2. Atualizar:

   sudo apt update && sudo apt dist-upgrade
   

3. Agora instale normalmente:

   sudo apt install python3-pip
   

4. Verifique se está instalado:

   pip3 --version
   

Isso deve resolver isso.
