I'm trying to do a distribution upgrade from Debian 6 to 7 and am having some issues with some packages I created and installed with checkinstall.  When doing the upgrade I get the following message:Preparing to replace python 2.6.6-3+squeeze7 (using .../python_2.7.3-4+deb7u1_all.deb) ...Unpacking replacement python ...dpkg: error processing /var/cache/apt/archives/python_2.7.3-4+deb7u1_all.deb (--unpack): trying to overwrite '/usr/bin/2to3', which is also in package python3.4.0 3.4.0-1This is due to the 2to3 installed in my python3.4.0 package.  I created and installed that package with this line:checkinstall -D --fstrans=no --dpkgflags=--force-overwrite \    --maintainer=tim@example.com --backup=yes \    --pkgname=python3.4.0 --pkgversion=3.4.0 make installIn hindsight it probably wasn't the best idea to use --force-overwrite but that was the only way I could get the package to install.I'd like to finishing installing the python_2.7.3-4+deb7u1_all package but tell it to use the file installed by python3.4.0 and not overwrite it.  Additionally, I'd like to repackage my python3.4.0 so I can properly install it without using --force-overwrite and tell the system to use the newest version of 2to3 instead of the one provided by the py2.7 package. (hopefully to avoid further issues later)
checkinstall package conflicts with python
