Package: python-mock-doc Version: 0.7.2-1 Severity: serious User: trei...@debian.org Usertags: edos-file-overwrite
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 python-mock. Unpacking python-mock (from .../python-mock_0.6.0-1.1_all.deb) ... Setting up python-mock (0.6.0-1.1) ... Processing triggers for python-support ... Selecting previously deselected package python-mock-doc. Unpacking python-mock-doc (from .../python-mock-doc_0.8.0-2_all.deb) ... dpkg: error processing /var/cache/apt/archives/python-mock-doc_0.8.0-2_all.deb (--unpack): trying to overwrite '/usr/share/doc-base/python-mock', which is also in package python-mock 0.6.0-1.1 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-base/python-mock The -doc package is a recent addition: python-mock (0.7.2-1) unstable; urgency=low * Ship documentation in separate package. The following relationships are currently defined: Package: python-mock-doc Conflicts: n/a Breaks: n/a Replaces: 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: python-mock-doc Breaks: python-mock (<< 0.7.2) Replaces: python-mock (<< 0.7.2) Cheers, Andreas PS: for more information about the detection of file overwrite errors of this kind see http://edos.debian.net/file-overwrites/.
