apt install python-pip, Unable to locate package – Ubuntu

When trying to install pip on Ubuntu with

sudo apt install python-pip

get the following error

Unable to locate package python-pip

Does the same thing for other basic packages. One of which was nasm “Dependency for Chipsec”

Issue ended up being that the Community-maintaned source was not enabled. Enabled via the Software & Updates. Should be able to search for it and it should come up.
