Package openstack-dashboard-ubuntu-theme fails to be removed

[Dr. Jens Harbott]

If the config for the dashboard or apache2 in general is not working, the removal of openstack-dashboard-ubuntu-theme fails because there is no graceful error handling in the postrm script. E.g. I am getting:

# apt-get -q -y purge openstack-dashboard-ubuntu-theme
    STDOUT: Reading package lists...

    The following packages will be REMOVED:

    dpkg: error processing package openstack-dashboard-ubuntu-theme (--remove):
     subprocess installed post-removal script returned error exit status 1
    Errors were encountered while processing:

The expected result would be to ignore any errors in the postrm script and successfully complete the removal.

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

I believe this has been fixed since Newton, when the openstack-dashboard-ubuntu-theme package was folded into the openstack-dashboard package. The package no longer collects/compresses static assets in the postrm script.
