I am trying to use my 24-word seed and password to integrate a Trezor hardware wallet with Electrum 2.6.4. with one machine I was able to install ok. Then I try to install on another machine, I am using the install wizard restore hardware wallet from pre-existing wallet, but I get the
no module named trezorlib.qt.pinmatrix
error. This is on Ubuntu Linux 14.04
Does anyone know where to find this module, how to download it, etc?
