I'm trying to run this code to view the files in this directory and save the results as output but this line is throwing an error upon execution.
Can anyone help me solve this and understand the issue?

Environment(s)
Ubuntu 20.04 & Debian 10 with Python 3.8 or 3.7, respectively.
Postgresql versions 11, 12, and 14 have been tried.
Psycopg2-binary 2.8.6
Overview
I'm attempting to install a Django project, and I'm getting this error:
psycopg2.errors.UndefinedFile: could not open extension control file "/usr/share/pgsql/extension/citext.control": No such file or directory
The psycopg devs informed me this is likely an issue with the postgresql-contrib libraries. Similarly, others have been able to fix this error by installing postgresql-contrib, however, this does not work for me. I've also tried installing postgresql-12.
I can see that citext.control is available in /usr/share/postgresql/12/extension/citext.control, so I tried ln -s /usr/share/postgresql/12 /usr/share/pgsql with no effect.
I also ran CREATE EXTENSION citext; in Postgres, also without effect.
Any support with this would be greatly appreciated, as I was hoping to have this project live already!
Thanks so much.

Have you tried installing python3-psycopg2 from the packaging system instead?
My Ubuntu 20 setup has this installed, and postgresql connections work with django.
ii python3-psycopg2 2.8.4-2 amd64 Python 3 module for PostgreSQL
I had installed postgresql-contrib on the local django server rather than the remote DB server. Installing on the same server as Postgresql resolved the issue.
I get this error while retrieving the program I wrote with kivy.

From the urllib documentation:
exception urllib.error.ContentTooShortError(msg, content)
This exception is raised when the urlretrieve() function detects that the amount of the downloaded data is less than the expected amount (given by the Content-Length header). The content attribute stores the downloaded (and supposedly truncated) data.
In practice, it's likely that the VPN terminated the socket. You may need to implement retry/resume capability in your program.
I want to start my docker-compose and I always get this error.
Docker Desktop tells me I'm logged in. I also rebooted once and logged in again.
I don't quite understand why that's not possible. If I pull other Docker Containers in another project, everything works.
We dont use paython in our project.

I am not a professional developer... trying to save chromedriver to PATH variable so i can use selenium with python.
following this page for instructions on this page
https://medium.com/#himanshuagarwal1395/setting-up-environment-variables-in-macos-sierra-f5978369b255
I open bash_profile with nano .bash_profile
I made a directory user/mysusername/selenium/
then saved my file chromedriver in this directory with the python script i and using selenium with.
I have tried to save my path to the chromedriver.exe file as such
export PATH="/User/baldoa/selenium/ChromeDriver.exe:$PATH"
I follow the steps to save appropriately according to this page. I am not sure
i still get the following error :

If I try to do the same in the Python 2.7 installed in my Windows 7 system, it works fine.
Since i am a novice, its difficult for me to diagnose the problem. I tried to research it but still haven't got any answers.
So my questions are:
What is different in the windows system that urlopen() works there but not on Linux.
What needs to be done to ensure that urlopen() works on the Linux system. Its necessary for me that it works since the the program I am developing has some bash command calls and the program depends extensively on the proper working of urllib.
