Ubuntu – Unable to upgrade pip


I am new to Linux and Ubuntu.

I was trying to upgrade pip but ran into this…

$ sudo pip install --upgrade pip
Cannot fetch index base URL https://pypi.python.org/simple/

Any idea why?

pip install -U pip


pip install --upgrade pip

-U is shorthand for --upgrade.

Old answer:

The apt system and PyPI uses two different mechanisms.

In Ubuntu's repositories many modules of python are available as packages, but they are not much in numbers as compared to PyPI (The Python Package Index). To remain consistent about upgrading a package you need to consider the method you have used initially used to install it.

So if you have installed a package (module) from PyPI using pip then you should used pip to upgrade the package from PyPI (including pip itself). On the other hand if you have used apt system to install a module (as package) you need to use apt to upgrade that again.

In a nutshell, run the following to upgrade python-pip to the latest version :

sudo apt-get install python-pip
