Date: 2012-05-11 Architecture: amd64 Distribution: sid 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: WARNING: The following packages cannot be authenticated! libflann1 libflann1.7 Authentication warning overridden. Can not write log, openpty() failed (/dev/pts not mounted?) Selecting previously unselected package libflann1. (Reading database ... 10560 files and directories currently installed.)

Unpacking libflann1.7 (from .../libflann1.7_1.7.1-2_amd64.deb) ... dpkg: error processing /var/cache/apt/archives/libflann1.7_1.7.1-2_amd64.deb (--unpack): trying to overwrite '/usr/lib/libflann_cpp.so.1.7.1', which is also in package libflann1 1.7.1-1 configured to not write apport reports dpkg-deb: error: subprocess paste was killed by signal (Broken pipe) Errors were encountered while processing: /var/cache/apt/archives/libflann1.7_1.7.1-2_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) This is a serious bug as it makes installation fail, and violates sections 7.6.1 and 10.1 of the policy. An optimal solution would consist in only one of the packages installing that file, and renaming or removing the file in the other package. Depending on the circumstances you might also consider Replace relations or file diversions. If the conflicting situation cannot be resolved then, as a last resort, the two packages have to declare a mutual Conflict. Please take into account that Replaces, Conflicts and diversions should only be used when packages provide different implementations for the same functionality. Here is a list of files that are known to be shared by both packages (according to the Contents file for sid/amd64, which may be slightly out of sync): /usr/lib/libflann.so.1.7 /usr/lib/libflann.so.1.7.1 /usr/lib/libflann_cpp.so.1.7 /usr/lib/libflann_cpp.so.1.7.1 -Ralf.
