Após tentativa e erro, posso sugerir o seguinte:
sudo apt-get install python3-pip python3-pyqt4 \
python3-pyqt5 python3-pyqt5.qtsvg python3-pyqt5.qtwebkit
sudo pip3 install -U spyder
O resultado: você tem o Spyder3 instalado e a janela Sobre o Spyder contém
Spyder 3.2.4
...
Python 3.5.2 64bits, Qt 5.5.1, PyQt5 5.5.1 on Linux
