ubuntu debs missing ctdb_mutex_ceph_rados_helper

When --enable-ceph-relock is added to rules, and librados-dev is installed, dpkg-buildpackage reports this error:
ake[1]: Entering directory '/tmp/samba/samba-4.10.7+dfsg'

If the missing files are installed by another tool, please file a bug against it.
When filing the report, if the tool is not part of debhelper itself, please reference the
"Logging helpers and dh_missing" section from the "PROGRAMMING" guide for debhelper (10.6.3+).
(in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.gz)
Be sure to test with dpkg-buildpackage -A/-B as the results may vary when only a subset is built
For a short-term work-around: Add the files to debian/not-installed
dh_missing: missing files, aborting
make[1]: *** [debian/rules:251: override_dh_missing] Error 255
make[1]: Leaving directory '/tmp/samba/samba-4.10.7+dfsg'
make: *** [debian/rules:88: binary] Error 2

Adding
usr/lib/*/ctdb/ctdb_mutex_ceph_rados_helper
and
usr/share/man/man7/ctdb_mutex_ceph_rados_helper.7
to
/debian/ctdb.install
puts those files in the ctdb deb and corrects the above.

Thank you for your report. This issue is present in Debian too, and it would be best fixed in Debian; Ubuntu will then pick it up on the next merge. Would you mind filing a bug against Debian samba package please?

This has been fixed in Debian since 4.13.4+dfsg-1, which was merged into Ubuntu during the Impish cycle, so I'm marking this bug as Fix Released.

FWIW, this is the commit that fixed it in Debian:
