Package: libmemcached3 Version: libmemcached3/0.34-1 Severity: serious User: trei...@debian.org Usertags: edos-file-overwrite
Date: 2010-01-24 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! libmemcached3 libmemcachedprotocol0 Authentication warning overridden. Can not write log, openpty() failed (/dev/pts not mounted?) Selecting previously deselected package libmemcached3. (Reading database ... 12276 files and directories currently installed.) Unpacking libmemcached3 (from .../libmemcached3_0.34-1_amd64.deb) ... Selecting previously deselected package libmemcachedprotocol0. Unpacking libmemcachedprotocol0 (from .../libmemcachedprotocol0_0.37-1_amd64.deb) ... dpkg: error processing /var/cache/apt/archives/libmemcachedprotocol0_0.37-1_amd64.deb (--unpack): trying to overwrite '/usr/lib/libmemcachedprotocol.so.0.0.0', which is also in package libmemcached3 0:0.34-1 Errors were encountered while processing: /var/cache/apt/archives/libmemcachedprotocol0_0.37-1_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/libmemcachedprotocol.so.0 /usr/lib/libmemcachedprotocol.so.0.0.0 A similar problem exists with Version: libmemcached3/0.34-1 Version: libmemcachedutil0/0.37-1 dpkg: error processing /var/cache/apt/archives/libmemcachedutil0_0.37-1_amd64.deb (--unpack): trying to overwrite '/usr/lib/libmemcachedutil.so.0.0.0', which is also in package libmemcached3 0:0.34-1 Errors were encountered while processing: /var/cache/apt/archives/libmemcachedutil0_0.37-1_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) 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/libmemcachedutil.so.0 /usr/lib/libmemcachedutil.so.0.0.0 I assume that the bug is with the libmemcached3 package since it is involved in both problems. -Ralf.
