Package: coccinelle-doc Version: 1.0.0~rc12.deb-4 Severity: serious User: treinen@debian.org Usertags: edos-file-overwrite Date: 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 coccinelle. Unpacking coccinelle (from .../coccinelle_0.2.3.deb-1_amd64.deb) ... Setting up coccinelle (0.2.3.deb-1) ... Processing triggers for python-support ... Selecting previously deselected package coccinelle-doc. Unpacking coccinelle-doc (from .../coccinelle-doc_1.0.0~rc12.deb-4_all.deb) ... dpkg: error processing /var/cache/apt/archives/coccinelle-doc_1.0.0~rc12.deb-4_all.deb (--unpack): trying to overwrite '/usr/share/doc-base/coccinelle-manual', which is also in package coccinelle 0.2.3.deb-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/coccinelle-grammar usr/share/doc-base/coccinelle-manual usr/share/doc-base/coccinelle-options The following relationships are currently defined: Package: coccinelle-doc Conflicts: n/a Breaks: n/a Replaces: n/a I think this was caused by splitting out the -doc package: coccinelle (1.0.0~rc7.deb-4) unstable; urgency=low * Move pdf documentation and examples into a separate package 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: coccinelle-doc Breaks: coccinelle (<< 1.0.0~rc7.deb-4) Replaces: coccinelle (<< 1.0.0~rc7.deb-4) Cheers, Andreas PS: for more information about the detection of file overwrite errors of this kind see http://edos.debian.net/file-overwrites/.
