Installation fails under Debian Testing

[mtausig]

Describe the bug

If I am trying to run the installation procedures as outlined in the Quickstart section of the documentation, an error occurs du to some incompatibility in a Python library

To Reproduce Steps to reproduce the behavior:

1. Go to https://www.ghostwriter.wiki
2. Follow the installation instruction at https://www.ghostwriter.wiki/getting-started/quickstart
3. See error

$ ./ghostwriter-cli install

During handling of the above exception, another exception occurred:

Expected Behavior

Ghostwriter should be installed or the documentation should specify more clearly what the dependencies are and which distributions are supported.

Server Specs:

• OS: Kali Linux (equivalent to Debian Testing)
• Docker 20.10.14+dfsg1, docker-compose 1.29.2, docker-py 5.0.3
• Ghostwriter 3.0.0

Hey @mtausig,

There have been issues installing the pinned libraries on Kali in the past. Kali uses its own repositories and is often based on a fork of Debian that is one or two versions behind the latest Debian. This error is caused by an older version of six. Switching to Debian or Ubuntu should resolve this for you.

You can also try upgrading six for docker-py on Kali (ref: https://github.com/docker/docker-py/issues/2294).
