Failed to install pip3 dependencies (v1.7.3 or older)

Warning

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 --version

When pip is broken, the output will be similar to this:

Traceback (most recent call last): File "/usr/bin/pip3", line 11, in <module> load_entry_point('pip==20.0.2', 'console_scripts', 'pip3')() File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 490, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2854, in load_entry_point return ep.load() File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2445, in load return self.resolve() File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2451, in resolve module = __import__(self.module_name, fromlist=['__name__'], level=0) File "/usr/lib/python3/dist-packages/pip/_internal/cli/main.py", line 10, in <module> from pip._internal.cli.autocompletion import autocomplete File "/usr/lib/python3/dist-packages/pip/_internal/cli/autocompletion.py", line 9, in <module> from pip._internal.cli.main_parser import create_main_parser File "/usr/lib/python3/dist-packages/pip/_internal/cli/main_parser.py", line 7, in <module> from pip._internal.cli import cmdoptions File "/usr/lib/python3/dist-packages/pip/_internal/cli/cmdoptions.py", line 24, in <module> from pip._internal.exceptions import CommandError File "/usr/lib/python3/dist-packages/pip/_internal/exceptions.py", line 10, in <module> from pip._vendor.six import iteritems File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 82, in <module> vendored("requests") File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 36, in vendored __import__(modulename, globals(), locals(), level=0) File "/usr/lib/python3/dist-packages/requests/__init__.py", line 95, in <module> from urllib3.contrib import pyopenssl File "/usr/lib/python3/dist-packages/urllib3/contrib/pyopenssl.py", line 46, in <module> import OpenSSL.SSL File "/usr/lib/python3/dist-packages/OpenSSL/__init__.py", line 8, in <module> from OpenSSL import crypto, SSL File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1553, in <module> class X509StoreFlags(object): File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1573, in X509StoreFlags CB_ISSUER_CHECK = _lib.X509_V_FLAG_CB_ISSUER_CHECK AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

Fixing the issue

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.py sudo python3 get-pip.py

Please 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 --version pip 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 --upgrade

If you encounter the following issue when running the Filescan installation script:

ERROR: Failed building wheel for yara-python

To fix the the issue, run the following command to install yara-python library:

sudo pip3 install yara-python==4.2.3 --use-pep517
