Download error during buildout

On a 4.3.19 install i get the following error running bin/buildout after adding an egg to the "eggs" section of the buildout.cfg

user@host zeocluster]$ sudo -u plone_buildout bin/buildout

Had the same issue with a customer site...short story short: some moron removed the hachoir.* packages from PyPI for whatever reason. I found some forks of the orginal repos on Github and add them through checkouts using mr.developer....possibly there are some copies of the release packages around, somewhere.

Thank you for that very quick answer !!!

For me i thought the [SSL: CERTIFICATE_VERIFY_FAILED] is the problem ! But i will try your solution, thank you very much !

Ok, i have found hachoir.* python eggs in an old running plone installation. How do i "rescue" it ? What are the steps necessary to republish them on pypi ? Never did this before so thank you for any advice.

[root@webserver eggs]# ll|grep achoi

We have also been hit by this hachoir* stuff, I have put the tarballs we have in our buildout cache here: https://code.codesyntax.com/static/public/
