Answer 1

Try installing manually:

wget -P ~/.local/lib https://bootstrap.pypa.io/pip/2.7/get-pip.py
python2.7 ~/.local/lib/get-pip.py --user 
#if using bash
printf "\nPATH=\$PATH:~/.local/bin/" >> ~/.bashrc
source ~/.bashrc

Answer 2

pip has dropped a support to python 2.7. If you still want to use it for python 2.7, downgrading the pip will help you:

sudo easy_install pip==20.3.4

Answer 3

In newer versions of Ubuntu such as 20.04, python-pip is no longer a package. Therefore, the old:

sudo apt install python-pip

Will fail.

Here's how to work around this issue:

curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
python get-pip.py

Answer 4

Just go into terminal and type in:

sudo apt-get install python-pip

I know that this at least works on a raspberry pi.
