horizon fails authentication with keystone

Bug #1661456 reported by Jeremy Nauck
This bug affects 3 people
Affects Status Importance Assigned to Milestone
OpenStack Dashboard (Horizon)

Bug Description

This report is almost identical to https://bugs.launchpad.net/horizon/+bug/1637072

Chef allinone installation following directions here; https://github.com/openstack/openstack-chef-repo

Command line access works fine, but access from Horizon to many functions renders an error similar to "Error: Unable to retrieve usage information." in System -> Overview. Similarly trying to display flavors yields the error "Error: Unable to retrieve flavor list."

Attempting to create a Flavor will cause an exception with the message "Danger: There was an error submitting the form. Please try again."

This installation is running Newton on Ubuntu 16.04 with Horizon 10.0.

The Horizon operations are frequently logging errors like these when trying to create a new Flavor.

After following along in the Bug report 1637072 I attempted to replace python-novaclient with 7.1.0, but the error still persisted. I'm currently running python-novaclient 6.0.0 and it also seems to fail with similar errors.

Ok, some progress... I still had some lingering 7.1.0 artifacts. Cleaned everything up and reinstalled v6.0.0 and things seem much better now.

The analysis in the last bug report was accurate. The Chef install is pulling a later version of the python-novaclient and it doesn't seem to be compatible with Newton & Horizon v10.

I hit this bug from a component which I would think is unrelated (tacker), so it was difficult to narrow the problem, glad to find this bug. Yesterday I installed a newer version of Tacker, which also pulled this new version of python-novaclient. Now I'm not able to perform any nova-related tasks from horizon (unable to retrieve instances, unable to retrieve the flavors, etc).

This is my log from apache:

Please ensure that your installed libraries match those specified in the upper-constraints.txt file relevant to the version of Horizon you're running (see https://docs.openstack.org/developer/horizon/topics/install.html for how that works).

I´m with this same problem, in both Tacker and Horizon. I tried clearing all the installating and reinstalled Tacker changing the file requirements.txt with novaclient beeing 6.0.0, but no success. It was raised another problem with packet cryptography during the compilation (gcc).

It worth mentioning that I found out that the online Openstack installation procedure has changed late last week. I reinstalled openstack from scratch twice last week (20/feb and 25/feb) , and the last one was with some changes, for example using fernet. In both of them I caught the same problem.
