apt - Unable to locate package python-pip on live system

I am trying to install electrum on my Ubuntu live USB. Please forgive me because I am very new to this OS. I have also made a persistence 4GB space for installing software.

How can I get past this error? I tried using

sudo apt-get update

first, but I still get

E: Unable to locate package python-pip

when I try to install.

Two Methods:

• You can install through Ubuntu Software Center.

  
  
  
  

  1. Open Ubuntu Software Center and search for easy_install

     
     

     

  
  

  2. Highlight alternative Python package installer (python-pip) from the
     list and click Install

     
     

     

  
  

  3. You can check weather the installation was successful or not by
     giving the command

     
     

     which pip

     
     

     you will see the path of installed application, for example

     
     

     /usr/local/bin/pip

  
  



• Second method

  
  
  
  

  1. Open terminal by pressing CTRL+ALT+T and type the following:

     
     

     cd ~

     
     

     to navigate to your home directory.

  
  

  2. Then issue the below command:

     
     

     wget -P Downloads/ https://svn.apache.org/repos/asf/oodt/tools/oodtsite.publisher/trunk/distribute_setup.py

  
  

  3. Next step is to run the downloaded script. To do this, issue this
     command:

     
     

     sudo python Downloads/distribute_setup.py

  
  

  4. and type your user password when prompted (Please, note that your
     account needs to be a member of Administrators group in order to
     issue sudo).

  
  

  5. Hit Enter and let the script run.

  
  

  6. To ensure easy_install is installed, issue the command below:

     
     

     which easy_install

     
     

     The typical response in case the installation completed successfully
     would look something like this:

     
     

     /usr/local/bin/easy_install

  
  

  7. The next thing to do is use easy_install to install pip. For that
     you’ll need to issue:

     
     

     sudo easy_install pip

  
  

  8. Enter your password if prompted to confirm command.

  
  

  9. Let the installer run and once the installation is completed type:

     
     

     which pip

     
     

     This command should typically respond with something like this:

     
     

     /usr/local/bin/pip
