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.

Long version: Released is released

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.

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/
