"Some packages could not be installed" error while installing python3-pip on Ubuntu 16.04

Solution 1:

Just remove the python-pip-whl package and try again:

sudo apt-get remove python-pip-whl

Solution 2:

After searching a lot, I was finally able to install pip3 on my Ubuntu 16.04 machine by simply running these commands

sudo apt-get install python3-setuptools
sudo easy_install3 pip

Solution 3:

You have broken packages so use these steps:

  1. Fix broken packages:

    sudo apt -f install
    
  2. Update:

    sudo apt update && sudo apt dist-upgrade
    
  3. Now install normally:

    sudo apt install python3-pip
    
  4. Check if it installed:

    pip3 --version
    

That should fix that.
