NoSuchOptError: no such option in group neutron: auth_plugin

[Marc Van de Voorde]

Im' runnign openstack mitaka on a 3 node installation (controller, compute and network). I installed it first under ubuntu 14.04 and later under ubuntu 16.04, but both have the same error when I try to launch an instance.

The error I get is the same using horizon or the command "nova boot --image cirros --flavor 1 --nic net-name=test erste".

Errormessage from the command line is
ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<class 'oslo_config.cfg.NoSuchOptError'> (HTTP 500) (Request-ID: req-2c2bb960-feb8-45ed-a3d1-65b8833d9228)

I'm using the versions below:
 dpkg -l | grep nova
ii nova-api 2:13.0.0-0ubuntu5 all OpenStack Compute - API frontend
ii nova-common 2:13.0.0-0ubuntu5 all OpenStack Compute - common files
ii nova-conductor 2:13.0.0-0ubuntu5 all OpenStack Compute - conductor service
ii nova-consoleauth 2:13.0.0-0ubuntu5 all OpenStack Compute - Console Authenticator
ii nova-novncproxy 2:13.0.0-0ubuntu5 all OpenStack Compute - NoVNC proxy
ii nova-scheduler 2:13.0.0-0ubuntu5 all OpenStack Compute - virtual machine scheduler
ii python-nova 2:13.0.0-0ubuntu5 all OpenStack Compute Python libraries
ii python-novaclient 2:3.3.1-2 all client library for OpenStack Compute API - Python 2.7

That's the same like bug 1574988 which got resolved with [1] in Newton but not backported to Mitaka or Liberty.

Does this mean I need to upgrade to Newton to get it resolved? Is Newton already stable and available to use?

[Ryan Selden (ryanx-seldon)]

I will try and get the fix that was included in newton backported to Mitaka, which means you wouldn't have to updgrade.

[Marc Van de Voorde (mvdv95)]

Ok, thanks wil you le me know when this is done and how to install this fix, or is this done automatically? Sorry for the questions, but I'm rather new at using openstack.

Fix proposed to branch: stable/mitaka

Marc,

The patch proposed above will this problem, you just need to wait for it to be merged. Once it is merged to the mitaka branch, then you can re-download the new code for mitaka and you should be good.

[Marc Van de Voorde (mvdv95)]

Hello Ryan,

sorry again for the maybe stupid question, but how do I "redownload the new
code for Mitaka" to install the patch?

Regards,
Marc

    Fix NoSuchOptError when referring to conf.neutron.auth_plugin

    Backporting to Mitaka

    We already replaced 'auth_plugin' with 'auth_type'[1], now an
    oslo_config.cfg.NoSuchOptError will be threw up when referring to
    conf.neutron.auth_plugin.

    This commit replace the usage of conf.neutron.auth_plugin by
    conf.neutron.auth_type.

This issue was fixed in the openstack/nova 13.1.1 release.

[Markus Zoeller (markus_z) (mzoeller)]

That was a Mitaka bug only as the bug in Newton got fixed with bug 1574988

[Marc Van de Voorde (mvdv95)]

Hello,

I belive I managed to download the tar.gz file for nova 13.1.1, but cna you help me how to install it? Sorry for the basic question, but I'm new to openstack.

Regards,
Marc

[Marc Van de Voorde (mvdv95)]

Hello,

Thansk to all how helped to get this fix in Mitaka :-).

Regards,
Marc
