Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

There is a file conflict between the two packages:

Upstart install script needs to filter rbd-mirror files from ceph package:

    # Install upstart configurations using dh_installinit
    for conf in `ls -1 src/upstart/ceph*.conf | grep -v mds`; do \
        name=`basename $$conf | cut -d . -f 1`; \
        cp -v $$conf debian/ceph.$$name.upstart; \
        dh_installinit -pceph --no-start --name=$$name; \
    done

as it does for mds now.

Later ceph versions (>= yakkety) stopped shipping upstart configurations, so this only impacts on Xenial.
