python-profiler for Python 2.6 fails to overwrite python2.5 lib

Asked by Jason R. Coombs

I have Ubuntu Lucid with the deadsnakes PPA added for Python 2.7, 3.2, and 2.5. I've since found that I need a profiler on my host, so I attempted to install it with "aptitude install python-profiler" but got this error:

Why is python-profiler_2.6.5-0ubuntu1_all.deb trying to write to /usr/lib/python2.5 ? Is this a bug? Is there a recommended workaround?

sudo dpkg --force-all -i /var/cache/apt/archives/python-profiler_2.6.5-0ubuntu1_all.deb ; sudo apt-get -f install

There is a file in 2 packages, Ubuntu doesn't like that. I suggest you report this to the PPA maintainer so this conflict can be resolved.

Maybe I should have been more explicit with my first question:

Why if Ubuntu Lucid ships with only Python 2.6 would any of its packages (including python-profiler) try to install a file into /usr/lib/python2.5 ?

Not sure, backward compatibility maybe?

Does it make sense that python-profiler in the multiverse should be adding profiling modules for versions of Python which are not available in that repo? That is, it seems more appropriate for deadsnakes to include the file than for python-profiler to do so.
