[Bug 1946653] Re: 15.2.12-0ubuntu0.20.04.1 uses ceph 15.2.13 instead

[Frank Villaro]

Indeed you were right.

So on a new ubuntu 20.04 machine (in my case dockerfile), installing
only ceph-fuse=15.2.13-0ubuntu0.20.04.2 results in the following
installed packages:

root at 62e110785d62:/app# apt policy ceph-fuse
ceph-fuse:
  Installed: 15.2.12-0ubuntu0.20.04.1
  Candidate: 15.2.12-0ubuntu0.20.04.1
  Version table:
 *** 15.2.12-0ubuntu0.20.04.1 100
        100 /var/lib/dpkg/status
root at 62e110785d62:/app# apt policy librados2
librados2:
  Installed: 15.2.13-0ubuntu0.20.04.2
  Candidate: 15.2.13-0ubuntu0.20.04.2
  Version table:
 *** 15.2.13-0ubuntu0.20.04.2 100
        100 /var/lib/dpkg/status

which results in the following stack trace.

The problem is fixed by installing a ceph-fuse==15.2.13-0ubuntu0.20.04.2
, however I still think that 15.2.12 with librados2 15.2.13 shouldn't
coexist.

Cheers

Title:
  15.2.12-0ubuntu0.20.04.1 uses ceph 15.2.13 instead

Status in ceph package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I currently have the ceph == 15.2.12-0ubuntu0.20.04.1 package
  installed:

  ```
  $ apt show ceph-fuse
  Package: ceph-fuse
  Version: 15.2.12-0ubuntu0.20.04.1
  ```

  However, when launching ceph, I see:
  ```
  $ ceph-fuse xxxxx
  2021-10-11T13:28:41.510+0000 7f0aaf60d080  0 ceph version 15.2.13 (c44bc49e7a57a87d84dfff2a077a2058aa2172e2) octopus (stable), process ceph-fuse, pid 110
  ceph-fuse[110]: starting ceph client
  ```

  Commit c44bc49e7a57a87d84dfff2a077a2058aa2172e2 is not present on
  15.2.12 but only 15.2.13.

  The sources of the deb package show 15.2.12 but the compiled binary
  does not, so I'm a bit lost.

  Furthermore, the update from 15.2.11-0ubuntu0.20.04.1 to
  15.2.12-0ubuntu0.20.04.1 introduced a serious bug (segfault) that
  makes no sense because the diff between the two git tags doesn't show
  anything related to my bug.

  
  Thanks and cheers !
