I was following a tutorial online for python and it had me do this:

akclark@enceladus:~$ pip install virtualenv

But I got the following:

Command 'pip' not found, but can be installed with:

sudo apt install python-pip

Easy enough, right? So I try it..

akclark@enceladus:~$ sudo apt install python-pip

But I get an error...

Reading package lists... Done
Building dependency tree Reading state information... Done
E: Unable to locate package python-pip

What am I doing wrong?

EDIT: Per Comments I have tried sudo apt update

EDIT2: I tried apt-cache madison python-pip and got 

N: Unable to locate package python-pip

EDIT3: grep '^deb ' /etc/apt/sources.list showed

deb http://archive.ubuntu.com/ubuntu bionic main 
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main

You have to enable universe category which contains python-pip package.

As David suggested, if you have software-properties-common installed, You can use this command to add universe category to your sources file:

sudo add-apt-repository universe

Then:

sudo apt update
sudo apt install python-pip

However if you rather to add it manually or you don't have add-apt-repository command available to run then follow these instructions:

Open /etc/apt/sources.list using an editor, for example nano:

sudo nano /etc/apt/sources.list

then add universe at the end of each line, like this:

deb http://archive.ubuntu.com/ubuntu bionic main universe
deb http://archive.ubuntu.com/ubuntu bionic-security main universe 
deb http://archive.ubuntu.com/ubuntu bionic-updates main universe

Press Ctrl+o to save the file. Press Ctrl+x to quit nano.

then run:

sudo apt update

and finally:

sudo apt install python-pip
