• TREZOR Firmware 1.4.0 — GPG decryption support

Installation

First, make sure that the latest trezorlib Python package is installed correctly (at least v0.6.6):

$ apt-get install python-dev libusb-1.0-0-dev libudev-dev
$ pip install -U setuptools
$ pip install Cython trezor

Then, install the latest trezor_agent package:

$ pip install trezor_agent

Or, directly from the latest source code (if pip doesn't work for you):

$ git clone https://github.com/romanz/trezor-agent && cd trezor-agent
$ python setup.py build && python setup.py install

Finally, verify that you are running the latest TREZOR firmware version (at least v1.4.0):

$ trezorctl get_features | head
vendor: "bitcointrezor.com"
major_version: 1
minor_version: 4
patch_version: 0
...

If you have an error regarding protobuf imports (after installing it), please see this issue.
