Basically, the title. I want to upgrade pip because I cannot get new packages in python because it is obsolete.
When I try to run pip3 install --upgrade pip from the Ubuntu terminal, this happens:
    Collecting pip
  Using cached pip-9.0.3-py2.py3-none-any.whl
Installing collected packages: pip
  Found existing installation: pip 9.0.1
    Uninstalling pip-9.0.1:

  Rolling back uninstall of pip

You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
How should I solve this problem? I tried to purge pip and reinstall it,but to no avail.
Edit: Also, tried the upgrade command with pip too, but it didn't seem to work.
