Failed to install pip3 dependencies (v1.7.3 or older)
This page only applies for v1.7.3 or older. Starting from v1.7.4, all Python dependencies are bundled into the release artifact.
If you encounter the following issue when running the Filescan installation script:
Fatal error: failed to install additional pip3 dependencies. Exiting...then very likely, the pip package manager is broken on your Ubuntu installation due to a bug in the pyopenssl Python package.

First of all, run this command to check if pip is in a broken state:
pip3 --versionWhen pip is broken, the output will be similar to this:

To fix the broken pip, run these commands to remove the python3-pipapt`` package and install the latest pip from pypa.io :
sudo apt remove python3-pip wget https://bootstrap.pypa.io/get-pip.pysudo python3 get-pip.pyPlease reboot your system (or log out and log in again), then check if pip is working.
You should see a pip version number like this:
pip3 --versionpip 23.0.1 from /usr/local/lib/python3.8/dist-packages/pip (python 3.8)It is also recommended to upgrade the pyopenssl package to avoid this issue in the future:
sudo pip3 install pyopenssl --upgradeIf you encounter the following issue when running the Filescan installation script:
ERROR: Failed building wheel for yara-pythonTo fix the the issue, run the following command to install yara-python library:
sudo pip3 install yara-python==4.2.3 --use-pep517
