To run FIT on Kali Linux inside Virtualbox (7.0) where python 3.11 was already installed, I did do the following steps.

1. Check Kali version

$ lsb_release -r
No LSB modules are available.
Release:        2023.3

2. Install Visual Studio Code

To install Visual Studio Code I followed the steps outlined in this guide as shown below:

$ sudo apt-get install wget gpg
$ sudo install -D -o root -g root -m 644 packages.microsoft.gpg /etc/apt/keyrings/packages.microsoft.gpg
$ sudo sh -c 'echo "deb [arch=amd64,arm64,armhf signed-by=/etc/apt/keyrings/packages.microsoft.gpg] https://packages.microsoft.com/repos/code stable main" > /etc/apt/sources.list.d/vscode.list'
$ rm -f packages.microsoft.gpg
$ sudo apt install apt-transport-https
$ sudo apt update
$ sudo apt install code

3. Install Python 3.11 by Pyenv

Install dependencies

I installed all these packages because at first builds I had the problems with different dependencies (eg. lzma, sqlite, openssl)

$ sudo apt build-dep python3          
$ sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
  libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
  xz-utils tk-dev libffi-dev liblzma-dev python3-openssl git

Download and install Python 3.9

  • Once I've installed all the dependencies I downloaded the source of Python 3.9 version
$ wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tgz
  • I used below commands to compile python source code.
$ tar xzvf Python-3.9.0.tgz
$ cd Python-3.9.0
$ sudo ./configure --enable-optimizations
$ sudo make altinstall

NB1: --enable-optimizations find more info here
NB2: make altinstall is used to prevent replacing the default python binary file /usr/bin/python.

4. Install FIT

Cloning repository and create virtualenvs with Poetry and python 3.9.

$ git clone https://github.com/fit-project/fit.git
$ cd fit
$ sudo apt-get python3-poetry 
$ poetry env use $(which python3.9)

NB: sudo apt-get python3-poetry I installed Poetry directly with apt-get

Install requirements with Poetry and run FIT

$ poetry install
$ poetry shell
$ $(which  python) fit.py #Run with user privileges
$ sudo env QTWEBENGINE_DISABLE_SANDBOX=1 $(which  python) fit.py #Run with root privileges

NB: If you use sudo to run FIT you need to set your user "Documents" as Case folder. As shown in the screenshot below.

Qt plugin "xcb" error

When I ran FIT for the first time I got this error:

```

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

Reinstalling the application may fix this problem. Aborted (core dumped)

```

Googling this error and I found several solutions.

  • The first thing I enabled QT Plugins debugging.
$ export QT_DEBUG_PLUGINS=1
  • After that I have tried to install/reinstall these packages at different times
$ sudo apt-get --reinstall install libqt5dbus5 libqt5widgets5 libqt5network5 libqt5gui5 libqt5core5a libxcb-xinerama0 libqt5x11extras5 libqt5x11extras5-dev libxcb-xinput0 libxcb-cursor0
  • Finally I also tried to make this symbolic link
$ sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/

I don't know exactly which of these tests made a solution, but I solved the error. In a future installation I will try to understand better!
