Failed to import plugin clustering

[Jared Baker]

When running any openstack client command I am provided with the following error, including the correct output of the command.

Example:

openstack image list

Status changed to 'Confirmed' because the bug affects multiple users.

[Corey Bryant (corey.bryant)]

This may simply just be python3-openstackclient needing a run-time dependency on python3-senlinclient.

[Jared Baker (shubjero)]

Hi Corey,

Looks like python3-senlinclient is already installed (but we dont use senlin). I would remove it but it wants to pull out all the openstack heat packages, which we use.

[Dr. Jens Harbott (j-harbott)]

Seems this is a version mismatch issue, I can reproduce this in a virtualenv with

python-openstackclient==3.18.0
python-senlinclient==1.7.0

The issue simply seems to be that senlinclient needs to be updated for stein, 1.7.0 is from rocky or older, if I install 1.9.0 or newer, the issue goes away. See https://releases.openstack.org/stein/index.html#stein-python-senlinclient

[Corey Bryant (corey.bryant)]

The cloud archive was missing the python-senlinclient backports for rocky, stein, and train so backported those packages. These are now available in corresponding -proposed pockets for testing:

Train: 1.11.0-0ubuntu1~cloud0
Stein: 1.9.0-0ubuntu1~cloud0
Rocky: 1.7.0-2ubuntu1~cloud0

sudo add-apt-repository cloud-archive:train-proposed
sudo add-apt-repository cloud-archive:stein-proposed
sudo add-apt-repository cloud-archive:rocky-proposed

It appears this fixes the issue for stein and train but not for rocky.

Thanks,
Corey

[Corey Bryant (corey.bryant)]

If anyone else would like to give this a test, please do so and report your findings back to this bug. Please note these packages are on their way to -proposed pockets and will be published within the next couple of hours.

python-senlinclient 1.7.0-2ubuntu1~cloud0 is now available in rocky-updates.
