Of the .sos above: (jessie)rene@frodo:/usr/lib/libreoffice/program$ for i in *py*so; do objdump -p $i | grep NEEDED; done NEEDED libpython3.4m.so.1.0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ NEEDED libpthread.so.0 NEEDED libdl.so.2 NEEDED libutil.so.1 NEEDED libuno_cppu.so.3 NEEDED libuno_cppuhelpergcc3.so.3 NEEDED libpyuno.so NEEDED libuno_sal.so.3 NEEDED libstdc++.so.6 NEEDED libm.so.6 NEEDED libgcc_s.so.1 NEEDED libc.so.6 NEEDED libpython3.4m.so.1.0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ NEEDED libpthread.so.0 NEEDED libdl.so.2 NEEDED libutil.so.1 NEEDED libuno_cppu.so.3 NEEDED libuno_cppuhelpergcc3.so.3 NEEDED libuno_sal.so.3 NEEDED libuno_salhelpergcc3.so.3 NEEDED libstdc++.so.6 NEEDED libm.so.6 NEEDED libgcc_s.so.1 NEEDED libc.so.6 NEEDED libdl.so.2 NEEDED libc.so.6 (jessie)rene@frodo:/usr/lib/libreoffice/program$ The build system of LO also only supports one python (and no, a hack like we had for python2/python3[2] doesn't scale.) Even if we did this python3.4-uno would conflict with python3.5-uno because of the common files above and moving the .sos above to a common package (libreoffice-core? python3-uno-core?) is a recipe for disaster (libpython3.4 vs. libpython3.5. OK, might not as bad as 3.3->3.4, but...) Note that python3-uno isn't really optional anymore, core functionality like wizards use python (for people who don't want it it's only recommended, though) and just in a extra package because it a) (also) is a module to use externally and b) because of the python policy. So LibreOffice always will use the default (or at least _one_ version if the default wasn't suitable.)

And of course the packages also conflicted.
