[ceph-users] Packaging bug breaks Jewel -> Luminous upgrade

Hi,

in Jewel, /etc/bash_completion.d/radosgw-admin is in the radosgw package
In Luminous, /etc/bash_completion.d/radosgw-admin is in the ceph-common 
package

...so if you try and upgrade, you get:

Unpacking ceph-common (12.2.8-1xenial) over (10.2.9-0ubuntu0.16.04.1) ...
dpkg: error processing archive ceph-common_12.2.8-1xenial_amd64.deb 
(--install):
  trying to overwrite '/etc/bash_completion.d/radosgw-admin', which is 
also in package radosgw 10.2.9-0ubuntu0.16.04.1

This is a packaging bug - ceph-common needs to declare (via Replaces and 
Breaks) that it's taking over some of the radosgw package -
https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-in-other-packages

The exact versioning would depend on when the move was made (I presume 
either Jewel -> Kraken or Kraken -> Luminous). Does anyone know?

[would you like this reported formally, or is the fix trivial enough to 
just be done? :-) ]

Regards,

Matthew
