How can I update pip3 to its latest version in Ubuntu 18.04?

Question

I get this error when running

pip3 install -U pip

Output:

Requirement already up-to-date: pip in ./dlenv/lib/python3.6/site-packages (10.0.1)
launchpadlib 1.10.6 requires testresources, which is not installed.

I have searched in apt and testresources seems to be installed already.

apt search testresources
Sorting... Done
Full Text Search... Done
python-testresources/bionic,bionic 2.0.0-2 all
  PyUnit extension for managing expensive test fixtures - Python 2.x

python3-testresources/bionic,bionic 2.0.0-2 all
  PyUnit extension for managing expensive test fixtures - Python 3.

I've gone through this GitHub issue, which was not clear with a solution.

Thanks, that fixes it. Wonder why it was not automatically installed as a dependency for pip3. Please add as answer. — Sebin Benjamin, Jul 12 '18 at 04:20
it supposes to install package with python installation. not sure what went wrong — jits_on_moon, Jul 12 '18 at 04:23
In case it helps someone: In my case (november 2018) it was solved by adding "universe" to apt sources (see [this answer](https://askubuntu.com/a/1061488/865083)). — Ralf, Nov 29 '18 at 19:48

I suggest installing pip by the PyPA guide on Ubuntu 18.04, since the pip version is too old if we install it by sudo apt install python3-pip.

The following work for me:

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

# python get-pip.py

BTW, the default location of pip is /usr/local/bin/pip, in case can't find the PATH.

Try this:

sudo apt-get remove python-pip python-dev

This will remove the pip and Python. Then install the required version of Python and pip.

I've installed it freshly. I'm asking the correct way to update pip3, not reinstall. – Sebin Benjamin Jul 12 '18 at 04:02
