Ubuntu 20.04 minimal: "Unable to locate package python-pip"

  • 772

Launching some small VMs in GCP and thought I would give Ubuntu 20.04 LTS minimal a try. After doing an "apt update; apt upgrade" I'm able to install packages like Apache, but having zero luck with PIP:

root@ubuntu-rr58:/home/me# apt install python-pip
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package python-pip

I have verified the Universe, Multiverse and Restricted repositories are available:

root@ubuntu-rr58:~# grep ^deb /etc/apt/sources.list
deb http://us-central1.gce.archive.ubuntu.com/ubuntu/ focal main restricted
deb http://us-central1.gce.archive.ubuntu.com/ubuntu/ focal-updates main restricted

  1. The package is called python3-pip. Python 2.7 is not shipped anymore with Ubuntu 20.04, nearly all python related packages are now called python3-*.

  2. To get the Python 2 version of pip back, you can use get-pip, which is a single script that downloads and installs the latest version of pip (for Python 2 or 3, whichever version you run the script with):

    $ curl -O https://raw.githubusercontent.com/pypa/get-pip/master/get-pip.py
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

$ python get-pip.py 
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

    Uninstalling pip-20.1:

  WARNING: The scripts pip, pip2 and pip2.7 are installed in '~/.local/bin' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed pip-20.1

    Then add ~/.local/bin/ to your PATH (e.g. in your ~/.bashrc):

    PATH=$HOME/.local/bin/:$PATH

    After that you should have a working pip command for Python 2. Or use pip2 / pip2.7 if you want to make sure you're not targeting Python 3.
