15.2.12-0ubuntu0.20.04.1 uses ceph 15.2.13 instead

[Frank Villaro]

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 !

What version of the librados2 package do you have installed? ceph-fuse depends on librados2, which comes from the same ceph source package. It's possible the version number comes from the library and not from ceph-fuse.

An apport report for this crash would be most helpful in tracking it down.

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@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@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.
