Errors were encountered while processing: /var/cache/apt/archives/libcblas3_3.2.1+dfsg-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/x86_64-linux-gnu/libcblas.so.3 This bug has been filed against both packages. If you, the maintainers of the two packages in question, have agreed on which of the packages will resolve the problem please reassign the bug to that package. You may then also register in the BTS that the other package is affected by the bug. -Ralf.
