pip3 not getting installed on Ubuntu

Hi I am trying to install pip3 on Ubuntu using the following commandsudo apt install python3-pip

and in response I am getting the following output

Error Image

Package python3-pip is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another source

E: Package 'python3-pip' has no installation candidate

I just want to install pip3 , please provide a way for solving this!

Help appreciated!
