DevStack Newton openstack client - barbican oslo.utils related errors

Hello Everyone,

I'm using Ubuntu 16.04 to build Newton based DevStack single VM installation. DevStack is working fine, but running the openstack list command returns error messages like this one...

Could not load EntryPoint.parse('secret_container_create = barbicanclient.barbican_cli.containers:CreateContainer')
Could not load EntryPoint.parse('secret_container_delete = barbicanclient.barbican_cli.containers:DeleteContainer')
Could not load EntryPoint.parse('secret_container_get = barbicanclient.barbican_cli.containers:GetContainer')
Could not load EntryPoint.parse('secret_container_list = barbicanclient.barbican_cli.containers:ListContainer')

Running the openstack client with --debug option, I've discovered the following conflict:

VersionConflict: (oslo.utils 3.16.0 (/usr/local/lib/python2.7/dist-packages), Requirement.parse('oslo.utils>=3.18.0'))

Changing the oslo.utils version from 3.16.0 to 3.18.0 in the requirements/general-requirements.txt file, and rebuilding the stack produced different kind of erros.

I've also tried to remove barbican from my configuration, but openstack client still reports an error. Is there any way to get this sorted out?

Thank you in advance!

Thank you for your answer!

I've started from the minimal Ubuntu VM, and all the tools including python and openstack client came as part of the devstack installation (after running ./ I'm not sure how to modify the devstack environment, or check for multiple python versions in devstack. By "removing barbican", I'm refering to commenting out the barbican related devstack lines in the local.conf, and then pefroming the ./, ./ followed by ./ The environment I'm working on will be used for training. It's important that system builds properly from the simple ./ command, instead of modifying particular configuration files. I will try to delete barbicanclient from the devstack, and will try to rebuild.

Best Regards,

Hi, I think the issue is related python-barbicanclient dropped support of Python 2.6 in commit I see that you have 2.7, but there might be several (/conflicting...) python versions on your system

A different sort of workaround on that would be to downgrade or uninstall python-barbicanclient. There might have been upgrade of python-barbicanclient as possible way forward, but according to what I see it is not the case. You mentioned that you tried to remove barbican (/barbicanclient?). For sure you shouldn't see things related to 'secret_container_get' once you don't have setup.cfg in barbicanclient installation.
