I tried installing python-requests earlier using

sudo apt-get install -y python-requests

and I get

Unable to locate package python-requests

I know this is a common question, but I've tried everything I could find: I ensured I have all repositories enable (Main, universe, etc.). Next, I tried installing python-pip in order to use pip instead of apt, but I got the same error when trying to install python-pip as with python-requests. After that, I used

sudo apt-cache search python-requests
sudo apt-cache search python-pip

to try to see if I had the name wrong or something, but could not locate either. I tried installing

 sudo apt-get install software-properties-common

as some stackoverflow question recommended in addition to running sudo apt-get update many times. Additionally, I ensured that my standard python does indeed point to python-2.7. Any help would be much appreciated!
