How to install Python package installer PIP on Ubuntu 20.04 Linux

Question

Trying to install pip with Ubuntu version 20.04 , Python version 3.8 on my Oracle virtual box. Tried everything to install pip but failed

Steps tried

$ sudo apt update
$ sudo apt install python3-pip

Also tried

$ sudo apt-get install python3-pip

Error both times

python3-pip is not available but is being used by another candidate. This may mean that the package has been obsolete, has been missing or is only available from another source.

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