Now say I want to rename the -foo suffix into -bar for both package python-foo and python-foo-dbg. The debian developer's reference suggests to Conflicts/Replaces/Provides the old name and change the name of the package to the new name in the corresponding d/control entries. I tried it and it worked well for python-foo to python-bar. However, dpkg does not handle the transition from python-foo-dbg to python-bar-dbg properly. You can find more information about the dpkg commands and modifications to d/control of the package in the original post linked above.

The modifications you made look all right too me:

Package: python-pyfftw-dbg
Architecture: any
Priority: extra
Section: debug
Depends:
${misc:Depends},
${python:Depends},
${shlibs:Depends},
python-pyfftw (= ${binary:Version})
Recommends:
python-dbg,
python-numpy-dbg
Provides: python-fftw3-dbg
Conflicts: python-fftw3-dbg
Replaces: python-fftw3-dbg

We probably need more information about this. You only wrote that "dpkg fails to perform the upgrade". But what exactly did you do, and how did it fail?

Basically, if I install python-fftw3 and call `dpkg -i python-pyfftw.deb`, then dpkg figures out the replacement, uninstall python-fftw3 and configure and install python-pyfftw.

If I install python-fftw3-dbg, and python-fftw3 automatically as a result the dependency, then `dpkg -i python-pyfftw.deb python-pyfftw-dbg.deb` does figure out the replacement of the -dbg package but fails on the main package. Then calling the same command a second time, dpkg works out the replacement of the main package. So essentially, I need to first call `dpkg -i` on the -dbg package and then call it a second time on the main package

I would expect dpkg to be smart and figure out that both the -dbg and main package should be replaced at once, and though this was not happening because something is wrong in my d/control. Maybe this is beyond dpkg's job and apt or aptitude would handle that just fine.

Thoughts ?
