Electrum falla al iniciarse, no se puede actualizar Python, no se puede eliminar Electrum

Tengo Ubuntu 16.04. Mi antigua billetera Electrum falla al iniciar, pero no puedo instalar la última versión de Electrum porque requiere Python 3.6.

:~/Downloads/Electrum-3.3.6$ ./setup.py
Error: Electrum requires Python version >= 3.6.1...

No puedo actualizar Electrum porque Python es la versión más nueva:

:~/Downloads/Electrum-3.3.6$ sudo apt-get install python3.6

Y tampoco puedo eliminar Electrum para instalar una nueva versión:

:~/Downloads/Electrum-3.3.6$ sudo apt remove electrum
