I'm attempting to set up flask to serve as a local webpage to interface with my pi, but for some reason it keeps returning errors when trying to download flask:
sudo pip install flask -v

Does anyone know what's going on here, and how to fix it?

Thanks to Joan for the answer -
Running sudo apt-get update seemed to fix any issues with installing flask.
