Answer 1

Since Python 2 is past its end-of-life, few packages for Python2 are included in 20.04. You have to install pip for Python 2 manually:

First, install Python 2:

sudo apt install python2

Then, follow https://pip.pypa.io/en/stable/installing/ , using python2:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python2 get-pip.py

You can run the second step with sudo. If you don't use sudo, you'll need to change PATH, as suggested by the installation message. Alternatively, and possibly better (since it doesn't change PATH), use

python2 -m pip

whenever you need pip2.
