+ In a host where ceph-mds is installed, upgrading from 14.2.11-0ubuntu0.19.10.1~cloud4 to 15.2.8-0ubuntu0.20.04.1~cloud0 fails with:

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
The problem happens because /usr/bin/cephfs-data-scan is provided by
ceph-mds in 14.2.11-0ubuntu0.19.10.1~cloud4:
# dpkg -S /usr/bin/cephfs-data-scan
ceph-mds: /usr/bin/cephfs-data-scan
However in 15.2.8-0ubuntu0.20.04.1~cloud0 it is provided by ceph-common:
# dpkg -S /usr/bin/cephfs-data-scan
ceph-common: /usr/bin/cephfs-data-scan
A quick workaround is to temporarily remove ceph-mds before the upgrade
(dpkg -r ceph-mds) and then perform the upgrade process using apt
install. It will upgrade all packages and reinstall ceph-mds.
