Karbor dashboard "no module named icalendar.cal" error

[Eric Miller]

Kolla-Ansible version 6.1.0 (with respective Kolla 6.1.0)
Images from source, built very recently (August 12th, 2018?)

After selecting Karbor as an installation option in globals.yml, the installation succeeds, but loading the Horizon interface results in an error: no module named icalendar.cal

I included the Traceback window contents below.

Hi, as I understand this bug, is a bug in karbor-dashboard requirements. They need to add icalendar into their requirements.txt file.

I'll add karbor-dashboard as affected package so they can fix/opinate about this.

    Add icalendar into requirements

    icalendar package is required to karbor-dashboard to work.
    It is imported and used at
    https://github.com/openstack/karbor-dashboard/blob/bfcecfee68e43f903c00354bc7fd759dc71c04b1/karbor_dashboard/triggers/utils.py#L18

    If package is not included, horizon fails to start, this dependency
    should be fixed in karbor-dashboard side rather than in deployment
    tools/packagers.

This issue was fixed in the openstack/karbor-dashboard 1.2.0 release.

[alpha23 (alpha23)]

This is still present in the kolla/centos-source-horizon:rocky image, 65c00f5af1ca, from 8 weeks ago. This defect was fixed in the dashboard ~70 weeks ago. Why is the fix not in the centos/source image?

[Mark Goddard (mgoddard)]

Kolla pins versions of direct dependencies in images. If karbor-dashboard did not create a release on the stable/rocky branch including this fix, we will not pick it up.

We are looking at changing the policy to just track the stable branches from Ussuri, but will probably not apply that to older releases.
