How to install python cryptography 38.0.4 without pip on Ubuntu

Question

My pip has corrupted after trying to install Apache Airflow. Every time I am trying to use it I am getting the following message

Traceback (most recent call last):

Based on this answer, I need to downgrade cryptography. However I cannot do it using pip since I am getting the same error. I tried to download to my Ubuntu the wheel file from here; specifically cryptography-38.0.4-pp39-pypy39_pp73-manylinux_2_28_x86_64.whl. However, when I extracted it, there was no setup.py file inside it. The only way I can imagine installing it without using pip is moving the extracted files to the place python libraries are stored. However I cannot find the place where the old cryptography library was installed.

How to install the specific version on my machine without using pip and considering there is no setup.py file?

Edit the `crypto.py`, see https://stackoverflow.com/a/73932621/7976758 Found in https://stackoverflow.com/search?q=AttributeError%3A+%22module+lib+has+no+attribute+OpenSSL_add_all_algorithms%22 — phd, Mar 28 '23 at 12:01
@phd Removing the line causing the error does not solve the problem. It causes the next line to raise an error. Removing the next line doesn't help either. — BillTheKid, Mar 28 '23 at 12:09
@pdh Also, in the list of posts you provided the problem is solved mostly by using pip upgrade or something similar, but I am unable to use it. — BillTheKid, Mar 28 '23 at 12:14
Try creating a fresh venv and install the dependency into that one https://docs.python.org/3/library/venv.html — Jorge Ruiz Gómez, Mar 28 '23 at 12:38
@JorgeRuiz This is a solution because I can work inside a virtual environment, however I don't know how to solve the problem with the "global" `pip` — BillTheKid, Mar 28 '23 at 13:18

I found out where old cryptography library was installed using:

python3 -c "import cryptography; print(cryptography.__file__)"

I deleted the folder and pasted the cryptography version 38.0.4 that I had downloaded from the link above.
