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

Question

I get this error when running

$ pip3 install -U pip

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

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.

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
