uninstallation of ceph worked. however, upgrading was difficult it required:
sudo aptitude -enter the package selector Mark all upgradeable then mark ceph for reinstallation due to it being held back - dependency problem)
result: it forces the system to use only latest packages and install them overwriting existing files then after reboot.
then: sudo apt remove ceph*
