Trying to install python3-pip, which has no installation candidate

Question

Ubuntu 20.04.1 LTS Desktop

My default Python version was 2.7.18 for some reason. I would like to update it to Python3 so I can install python3-pip onto my desktop.

After running:

 sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 20

I get:

 update-alternatives: using /usr/bin/python3.8 to provide /usr/bin/python (python) in auto mode

My python version is: Python 3.8.5

The issue is still that when I run:

sudo apt install python3-pip
E: Package 'python3-pip' has no installation candidate

Does anyone have any recommendations?

In my bin for python i have: /usr/bin/python /usr/bin/python3 /usr/bin/python2

Solution

You may have to enable the universe repository first.

sudo add-apt-repository universe

Then run the following command to synchronize your package database.

sudo apt update

Finaly install pip3 with

sudo apt install python3-pip
