ContextualVersionConflict Requirement.parse('python-keystoneclient>=3.8.0'), set(['glance-store'])

[Ken]

During installation of Newton using DevStack, I have come across the error " ContextualVersionConflict: (python-keystoneclient 3.5.0 (/usr/local/lib/python2.7/dist-packages), Requirement.parse('python-keystoneclient>=3.8.0'), set(['glance-store']))". I am not sure but this seems to be a bug hence this report.

The log trace is attached :

[Alessandro Delfino (alessandro.delfino)]

I found the same error when running devstack from newton branch.

I changed the file upper-constraints.txt in /opt/stack/requirements with the one from the master: https://raw.githubusercontent.com/openstack/requirements/master/upper-constraints.txt

This bypass the error, but I think is only a workaround.

[Adolfo Duarte (adolfo-duarte)]

I have found this problem as well on ubuntu 16.04

[Faseela K (faseelak)]

I am getting the same error, while stacking ocata. However python-neutronclient requirements.txt is showing keystoneauth1 as 2.18

[Caisi LIU (caisil)]

@Sean Dague I encounter the same issue on newton.
I'd like to know, where should the "devstack version: ..."? devstack/.git/description?
What is the full description like?
devstack version: openstack-version.newton

Is this right?

Thanks.

[Dr. Jens Harbott (j-harbott)]

Given the age of the bug report, it is unclear whether this is still a valid issue. Please update with fresh logs if this issue still persists.
