python-pip package disappeared in Ubuntu 20.04
Solution 1:
python-pip package is no longer supported by Ubuntu as Python 2.7 is no longer supported. So forget that package. But you can still install it by issuing the following on terminal:
wget https://bootstrap.pypa.io/get-pip.py
python2 get-pip.py
As python3-pip package is supported, which provides pip3 command you can install it Python 3 with apt by:
sudo apt update
sudo apt install python3-pip
