Many pkgs have autodeps on ipython3, which are not justified, because they simply provide ipython-plugins, which can be used if ipython3 is installed, but are "ignored" otherwise. Something has to be done (rules in rpm-build-python3 or fixinf of the individual pkgs). apt> whatdepends ipython3 ipython3-4.0.0-alt3.1.1 python3-module-plotly-1.6.6-alt2.1 Depends: <python3.3(IPython.html)> ipython3-4.0.0-alt3.1.1 python3-module-pandas-highcharts-0.3.0-alt1.git20150228.1.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-oct2py-1.5.0-alt2.1.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-notebook-4.0.4-alt2.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-nbconvert-4.0.0-alt2.1.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-jupyter_console-4.1.0-alt1.dev.git20150812.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-ipyparallel-4.1.0-alt1.dev.git20150819.1.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-ipykernel-4.0.3-alt2.1.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-ipdb-0.8.1-alt1.dev0.git20130919.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-dautil-0.0.1-alt1.a18.2 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 ptpython3-0.20-alt1.git20150808.1 Depends: <python3.3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-sfepy-2015.1-alt1.git20150427.1 Depends: <python3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-rpy2-2.7.8-alt1.1 Depends: <python3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-rasterio-0.26.0-alt1.git20150811.1 Depends: <python3(IPython)> ipython3-4.0.0-alt3.1.1 python3-module-PyMca-5.0.0-alt1.git20150221.1.1 Depends: <python3(IPython)> ipython3-4.0.0-alt3.1.1 apt>
