Locust Installation error on Ubuntu 16.04 and Debian Stretch

Describe the bug

As far as I understand, Locust package has moved from locustio to locust. I was developing an Ansible role to install locust on a few of Debian family operating systems such as the following:

• Ubuntu 20.04
• Ubuntu 18.04
• Ubuntu 16.04
• Debian Buster
• Debian Stretch

Using python3’s pip, locust is successfully installed on Ubuntu 20.04, Ubuntu 18.04 and Debian Buster. However, it attempts to install locustio along with locust and errors out on Ubuntu 16.04 and Debian Stretch.

Expected behavior

Clean installation on Ubuntu 16.04 and Debian Stretch.

Actual behavior

Outputs below error (running locally within a docker container of ubuntu 16.04):

$ python3 -m pip install locust

Steps to reproduce

Install locust on an ubuntu 16.04 or debian stretch docker image.

OR try following:

docker run -it darkwizard242/ansible:ubuntu-16.04 /bin/bash -c 'python3 -m pip install locust' 

docker run -it darkwizard242/ansible:debian-stretch /bin/bash -c 'python3 -m pip install locust' 

Environment

• OS: Ubuntu 16.04 & Debian Stretch
• Python version: 3.5.2 (ubuntu 16.04) and 3.5.3 (debian-stretch)
• Locust version: Default (as failure at installation process with certain operating systems)

@heyman Can you delete the locust 0.0 package? I dont have permissions…

Once it is removed people should at least get a more reasonable error message. The reason for the strange error is that locust 0.0 (from 2018) states that it supports 3.5, but it just references locustio. “real” packages released as locust (starting with 1.0) dont support 3.5, so you get the only one that does.

A comment for others reading along: I received this error using python:3.9.0-slim-buster today and worked around it by using python:3.8.10-slim-buster in my Docker image instead, which worked.
