a little info, no answer yet:
ceph-mon depends on ceph-base which depends on python
I guess python -> python2.7 -> libpython2.7-stdlib -> libpython2.7-minimal, which does not include the .so (which is in libpython2.7)
Oddly, the only thing 'ceph' seems to add is 'ceph-osd', which only adds python-flask, which only depends on python
Updated by Nathan Cutler over 7 years ago
- Status changed from New to 17
Could this be caused by the way debian processes the ${python:Depends} macro? I see ceph-osd has it but ceph-mon does not. That might explain why the problem goes away when ceph-osd is installed.
I pushed a PR to test this hypothesis: https://github.com/ceph/ceph/pull/11507
Alfredo, can you test this PR easily?

Changing the priority for this. kraken is completely broken even if we install differently. A ceph-deploy install breaks like this:

This is with 11.0.2 which was just released.
There are a lot of tools (e.g. ceph-ansible) that require correct output from `ceph --version`)
Also note that this time it wasn't just a single component getting installed

Sounds like ceph-base should depend on libpython2.7?
Updated by Nathan Cutler over 7 years ago
/usr/bin/ceph is packaged in ceph-common (not ceph-base).
It's interesting that "apt-get install ceph" does cause the libpython2.7 package to be installed.
ceph-deploy is doing sudo env DEBIAN_FRONTEND=noninteractive DEBIAN_PRIORITY=critical apt-get --assume-yes -q --no-install-recommends install -o Dpkg::Options::=--force-confnew ceph-osd ceph-mds ceph-mon radosgw ( full line taken from http://tracker.ceph.com/issues/17579#note-4 ) -- this should be installing libpython2.7, too, via dependency resolution, since it is correctly bringing in ceph-common as a dependency.
I'm not familiar with Debian policy wrt Python, but shouldn't dpkg/APT be auto-detecting that ceph-common depends on libpython2.7 ?
Also, looking at the package description https://packages.debian.org/jessie/libpython2.7 it says "This package contains the shared runtime library, normally not needed for programs using the statically linked interpreter."
Updated by Kefu Chai over 7 years ago
ceph-common (which offers "ceph" cli) => python-rados => ${python:Depends}
but we should have added "${shlibs:Depends}" to the dependencies section of the python-* packages. i removed it in 48f4576de1825f5a386c0efd18e85a9fa919c2f0.
debian: remove ${shlibs:Depends} from python-* packages
- debian/control:
as we have listed the linked libraries in Depends section, for example,
python-rados depends on librados. and we don't need `dpkg-shlibdeps` to
help figure out shared library substvar dependencies for us. by removing
them, we can silence the warnings of
```
warning: dpkg-shlibdeps: package could avoid a useless dependency if
debian/python-rados/usr/lib/python2.7/dist-packages/rados.x86_64-linux-gnu.so
was not linked against libpthread.so.0 (it uses none of the library's
symbols)
```lpthread is introduced by `python-config --ldflags` but it turns out we* pacakges. but it's desirable to have less
are not using any symbols from pthread in the extension directly. and
pthread is included in glibc. so this does not added any extra
dependency to python
warnings.- debian/rules: exclude python-* packages from dh_shlibdeps, as we will
not use it to prepare the shlib deps substvars for these packages any
more.
and it turns out we failed to list all shared lib dependencies explicitly. so the fix is
- either put "${shlibs:Depends}" back, or
- list libpython2.7 or libpython3.5 explicitly
i'd suggest the former.

Kefu updated the PR, so it's ready to test.
