Title:

Status in ceph package in Ubuntu:
  Confirmed

Bug description:
  This issue is a continuation of
  https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/2065515

  
  On Ubuntu 24.04 lts we did upgrade Ceph to  19.2.0-0ubuntu0.24.04.1

  Previous release is : 19.2.0~git20240301.4c76c50-0ubuntu6

  whenever  upgrading (tested on 2 different clusters)  the ceph-mon
  ends up crashing repeatedly with the below stack error

   NOTE: a copy of the executable, or `objdump -rdS <executable>` is needed to interpret this.

  ```

  
  mitigation:
  a rollback to the previous release 19.2.0~git20240301.4c76c50-0ubuntu6 is still possible to restore service
