I'm running into the following error message when I do easy_install pip:

root@ff45b7b74944:/# easy_install pip
Searching for pip
Reading https://pypi.python.org/simple/pip/
Download error on https://pypi.python.org/simple/pip/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) -- Some packages may not be found!
Couldn't find index page for 'pip' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading [--https link here, like above--]
Download error on https://pypi.python.org/simple/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) -- Some packages may not be found!
No local packages or download links found for pip
error: Could not find suitable distribution for Requirement.parse('pip')

This is run in a docker container that runs on ubuntu:latest. I'm leaning towards the fact that it can't do openssl stuff (https link), but I'm not completely certain. If anyone has a solution or any troubleshooting methods, I'd love to find out.

adding RUN apt-get install ca-certificates to my Dockerfile worked for me.

  • @marcellothearcane that command depends on the distribution you're using. apt-get is used in debian/ubuntu distros (and probably others), but not all.

  • It was, (Ubuntu 20.04) but I'm afraid my computer was just being really weird. Aug 5, 2020 at 5:25


Added the following to the Dockerfile:

RUN mkdir /etc/pki
RUN mkdir /etc/pki/tls
RUN mkdir /etc/pki/tls/certs
RUN apt-get install wget
RUN wget http://curl.haxx.se/ca/cacert.pem
RUN mv cacert.pem ca-bundle.crt
RUN mv ca-bundle.crt /etc/pki/tls/certs

Fresh installation of below packages solved my problem

apt-get -yqq install build-essential libssl-dev libffi-dev python3-pip python3-dev gnupg
