as discussed in #openstack-kolla we'll run next try with --skip-tags kibana. The old kibana is still running and seems working.

I'll keep this issue updated.

**Environment**:
OS: Ubuntu 18.04
Kernel: 4.15.0-91-generic
Docker: 19.03.8
Type: source
Official images from Docker Hub, but retagged and pushed to our local nexus.

All other tasks within this upgrade went well!

[Mark Goddard (mgoddard)]

The task that failed has now been removed, so you won't hit this again.

[Alexander Diana (rouk)]

I am unsure about this task being removed, as it is still present and broken in master, among other brokenness related to this task.

I have patched the task to work and attached the new files, hopefully it helps someone and can be merged if needed.
