I am trying to install mininet-wifi. After downloading it, I have been using the following command to install it:

    sudo util/install.sh -Wlnfv

However, I keep getting the error:

    E: Unable to locate package python-pip

I have tried multiple times to download python-pip. I know mininet-wifi utilizes python 2 instead of python 3. I have tried to download python-pip using the command:

    sudo apt-get install python-pip

But that leads to the same error:

    E: Unable to locate package python-pip

Pip for Python 2 is not included in the Ubuntu 20.04 repositories.
You need to install pip for Python 2 using the get-pip.py script.

1. Start by enabling the universe repository:

sudo add-apt-repository universe

2. Update the packages index and install Python 2:

sudo apt update 
sudo apt install python2

3. Use curl to download the get-pip.py script:

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

4. Once the repository is enabled, run the script as sudo user with python2 to install pip :

sudo python2 get-pip.py

If an error occurs, as a fallback, the specific 2.7 version of get-pip.py can be used:

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

Pip will be installed globally. If you want to install it only for your user, run the command without sudo. The script will also install setuptools and wheel, which allow you to install source distributions

Verify the installation by printing the pip version number:

pip2 --version

The output will look something like this:

 pip 20.0.2 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
