Comment 3 for bug 1946653

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.

Cheers
