Architecture: amd64 Distribution: squeeze->wheezy (partial) upgrade Hi, automatic installation tests of packages that share a file and at the same time do not conflict by their package dependency relationships has detected the following problem: Selecting previously deselected package ipython. Unpacking ipython (from .../ipython_0.10-2_all.deb) ... Processing triggers for python-central ... Setting up ipython (0.10-2) ... Processing triggers for python-support ... Selecting previously deselected package ipython-doc. Unpacking ipython-doc (from .../ipython-doc_0.13.1-1_all.deb) ... dpkg: error processing /var/cache/apt/archives/ipython-doc_0.13.1-1_all.deb (--unpack): trying to overwrite '/usr/share/doc/ipython/examples/core/example-gnuplot.py', which is also in package ipython 0.10-2 This is a serious bug as it makes installation/upgrade fail, and violates sections 7.6.1 and 10.1 of the policy. As this problem can be demonstrated during partial upgrades from squeeze to wheezy (but not within squeeze or wheezy itself), this indicates a missing or insufficiently versioned Replaces+Breaks relationship. But since this particular upgrade ordering is not forbidden by any dependency relationship, it is possible that apt (or $PACKAGE_MANAGER) will use this erroneus path on squeeze->wheezy upgrades. Here is a list of files that are known to be shared by both packages (according to the Contents files for squeeze and wheezy on amd64, which may be slightly out of sync): usr/share/doc/ipython/examples/core/example-embed-short.py usr/share/doc/ipython/examples/core/example-gnuplot.py usr/share/doc/ipython/examples/core/ipython-sh.desktop usr/share/doc/ipython/examples/core/ipython.desktop usr/share/doc/ipython/examples/core/ipython_here_shell_extension.reg usr/share/doc/ipython/examples/core/leo_bridge_demo.leo.gz usr/share/doc/ipython/examples/core/seteditor.py The examples were recently moved around: ipython (0.12.1+dfsg-1) unstable; urgency=low * move all examples to ipython-doc The following relationships are currently defined: Package: ipython-doc Replaces: ipython-notebook (<< 0.12.1-1) Depends: ipython, libjs-sphinxdoc (>= 1.0) Breaks: ipython-notebook (<< 0.12.1-1) Conflicts: n/a The following relationships should be added for a clean takeover of these files (http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces): Package: ipython-doc Breaks: ipython (<< 0.12.1+dfsg) Replaces: ipython (<< 0.12.1+dfsg) Alternatively to the Breaks, the Depends could be made versioned (the Replaces is still needed): Package: ipython-doc Depends: ipython (= $(source:Version}) Replaces: ipython (<< 0.12.1+dfsg) Cheers, Andreas PS: for more information about the detection of file overwrite errors of this kind see http://edos.debian.net/file-overwrites/.
