I can't install releases of packages from devpi other than the latest release. All releases show up in the listening: $ devpi list package http: //devpi.corporate.com/orangetux/dev/+f/d15/d668a6cffc273/package-0.6.1-py2.py3-none-any.whl http: //devpi.corporate.com/orangetux/dev/+f/f9b/9f520a2c17633/package-0.6.0-py2.py3-none-any.whl http: //devpi.corporate.com/orangetux/dev/+f/7f1/5c7b906eace44/package-0.5.0-py2.py3-none-any.whl Installing version 0.6.1 goes without problem, but instaling an older release is not possible: $ pip install --upgrade --trusted-host devpi.corporate.com --find-links http ://devpi.corporate.com/dev --no-index package==0.6.0 Ignoring indexes: https://pypi.python.org/simple Collecting package==0.6.0 Could not find a version that satisfies the requirement package==0.6.0 ( from versions: 0.6.1) No matching distribution found for package==0.6.0 Is their something I'm missing?
