Title:
   Unable to load libceph_snappy.so due to undefined symbol
  _ZTIN6snappy6SourceE in snappy 1.1.9

Status in ceph package in Ubuntu:
  Confirmed

Bug description:
  After upgrading the Ceph cluster to Ubuntu 22.10 ("Kinetic"), the Ceph
  cluster shows a health error

  OSDs have broken BlueStore compression

  See also here:

  and here:

  https://bugs.gentoo.org/820611
  https://github.com/google/snappy/pull/144

  The reason for this seems to be that the underlying libsnappy library
  has disabled RTTI (whatever that is) in 1.1.9.

  I could solve this by downloading and installing an old version:

  wget http://de.archive.ubuntu.com/ubuntu/pool/main/s/snappy/libsnappy1v5_1.1.8-1build3_amd64.deb
  dpkg -i libsnappy1v5_1.1.8-1build3_amd64.deb

  On a more critical side note: This issue, for example, seems to be
  known for at least a year. I don't know who is responsible and I'm not
  implying the Ubuntu team is responsible, but the reality is: I have
  yet to experience a single Ubuntu version update without Ceph breaking
  one way or another. Isn't anyone testing this stuff?

  Sometimes it's the Ceph dashboard due to Python issues, sometimes it's
  this issue here, sometimes it's something else. But never ever have I
  done an Ubuntu update without Ceph breaking in some obscure way ;-(

  I never have problems with anything else. Not with MariaDB, not with
  PHP/FPM, not with Apache. Sorry for the rant - your hard work is of
  course really appreciated. Hope you understand it's a bit frustrating.
  Perhaps the Ubuntu or Ceph folks can sit together and find a way to
  make this a little bit more reliable in the future. Keeping fingers
  crossed.
