Thanks for taking your time to report this issue and help making Ubuntu better.
I am not able to reproduce this issue, as I was able to install both python3-pip and python-pip on my Ubuntu 16.04 system. Based on the error message (and that you have python-pip already installed) it seems to be some mismatch in the packages it suggests when you attempt to install python3-pip. Good call on running `sudo apt update` first, that normally sorts out mismatch issues. Could you please re-run that, and possibly install any missing updates. If the problem persists, I would be interested in the output of `apt policy python3-pip python-pip-whl` to see which package versions it will attempt to find and install. When reporting bugs in the future please use apport by using 'ubuntu- bug' and the name of the package affected.
