I downloaded the src rpm for ceph 13.2.0  and extracted it to look at the ceph.spec file

I think this section is giving you grief.  

%if 0%{?suse_version} >= 1500

%bcond_with python2

%else

%bcond_without python2

%endif

%if 0%{without python2}

%global _defined_if_python2_absent 1

%endif

By not setting  “defined_if_python2_absent”  it should use the python2 code, as far as I can tell.

See what happens if you comment it out, or remove it.

Subject: [Starlingx-discuss] python interpreter version problem.

Hi,

         When upgrading ceph to 13.2.0, i have resolved all deps package of new package, but now being stuck at python interpreter version.

         Now, starlingx just support python2, and don’t support more high python version. But ceph 13.2.0 need python3 interpreter to interpret corresponding ceph package.

         I have tried to modify python3 into python2.7 at ceph.spec file, but still don’t work.  

Does anyone know how to resolve it?

         Thanks for your help.
