+    sudo apt-get install python3
+    sudo apt-get install python3-pip
     sudo apt-get install python3-cryptography
     sudo apt-get install python3-pyqt5
     sudo apt-get install libsecp256k1-0
     sudo apt-get install cmake
+    sudo pip3 install virtualenv
     ./electrum-env
 
 Not pure-python dependencies
