Python 2 pip[2] uninstall pip removes /usr/bin/pip3

[elibroftw]

Description

we have pip2 and pip3 installed on our machines. If we remove pip from pip2, then /usr/bin/pip3 is also removed. python3-pip is not removed so installing python3-pip without force does not reinstate /usr/bin/pip3.

And sudo apt remove python-pip does not work because "Package 'python-pip' is not installed, so not removed"

Expected behavior

/usr/bin/pip3 should be left alone when uninstalling python2's pip

pip version

20.3.4

Python version

Python 2.7

OS

Ubuntu-20.04

How to Reproduce

Since this involves Python 2 and Ubuntu (which is based on Debian), I'll recommend you report this issue to the Ubuntu or Debian projects, with reportbug python3-pip (their reporting documentation). You can link to this issue in your bug report.

Closing this, since we don't support Python 2 upstream and this seems to involve Debian's packaging of pip and/or Python 2 provided by them.
