You need the python package installer “pip”. If you don’t have it you can install it on Debian systems:

sudo apt-get install python-pip

And now you can install the autocrypt package:

pip install --user autocrypt

And then make sure that ~/.local/bin is contained in your PATH variable.

See getting started with the command line.

Installation for development

If you plan to work/modify the sources and have a github checkout we recommend to create and activate a python virtualenv and issue once:

$ cd src
$ virtualenv venv
$ source venv/bin/activate
$ pip install -e .

This creates a virtual python environment in the “src/venv” directory and activates it for your shell through the source venv/bin/activate command.

Changes you subsequently make to the sources will be available without further installing the autocrypt package again.
